I am the user who copied your answer Manx. My original post did not answer the OP’s question, so I edited it to yours. I apologise for copying your answer without mentioning you. I have edited my answer to give credit to you for the original post, and I have recently visited this page for advice on how, and when to edit an incorrect answer. In retrospect, ...

How does voting work? There are three votes, but the votes are ranked. You select a first choice, a second choice, and a third choice. (It is possible to only make a first or a only a first and second choice.) You do not cast three equivalent votes. Once voting ends, initially only the first choices are considered. The candidate that comes in last is ...

As long as you don't submit the post, I don't see any harm in using the preview functionality of Stack Exchange to test your LaTeX code. But see Concerns about MathJax in proposed new SE editor – at the moment it's unclear whether that will continue to work. Otherwise, we have the Formatting Sandbox which can be used for this kind of stuff. Note that the ...

There is no such thing. Some people, however, feel that in order for a contribution to an old question that has already amassed some good answers, one needs to go the extra mile to prove that it's worth adding an answer. It follows that some people are easier on the draw when it comes to downvoting answers like that.

In your special case we can get away with the built-in \triangledown to represent the lines connecting each vertex. We can also make use of \odot to represent each ringed node: $$\begin{array}{ccc}\hline\text{Case}&\text{Coxeter diagram}&\text{Vertex configuration}\\\hline\text{1 ringed node}&{}^{\boldsymbol p}\hspace{-0.15cm}{\Huge\triangledown}... 20 It seems you purposefully chose a word that is similar to what according to you is an inappropriate word. It is not very clear why you even need to ask why this was changed. Basically you tried to place the name right next to the line of what is inappropriate but just to the appropriate side in your opinion. This is like somebody that puts their finger ... 16 In general, you can do the following: Downvote the answer If not already present, leave a comment indicating why the answer is incorrect (possibly with ways to improve it) If possible, post another answer which is correct Flagging is not the right option since it's not the moderators' job to determine whether an answer is correct or not. Relevant posts on ... 15 Use \mathcal I_1 to get \mathcal I_1. 15 Could you be a bit more specific about the situation in which you expect to get a comment. In the current revision you write: "I do not get a notification when someone writes a comment under an answer, where I commented too." AFAICT that is exactly how this is supposed to work - with one notable exception that if you and the OP are the only users ... 13 As @Zacky mentioned, there is a proposed FAQ on Meta Stack Exchange. That focuses on the facts; I wrote an answer to a similar question on Arqade about the advantages of both features: You should use the 'follow' feature when: you want to receive inbox notifications you want to keep the fact that you're following a post private you want to keep a reference ... 12 If the question you want to ask appeared in a Math contest (or contest training), then You should make it clear that the question is from a contest. Adding the contest-math tag is a good way of achieving that, but I recommend that you also make this explicit in either the question body or the title, because this affects how many users approach the question (... 12 Pare question to its basics Pare your problem down to the minimum core problem. Instead of asking for$$\frac{\sin 2 k \sqrt{3 + q^3}}{b! (b-2)!} \int\limits_{x=0}^{\infty} \frac{e^{-x^2/(2 \sigma^2)} \cos \sqrt{3 + \sqrt{y}}}{\sqrt[3]{2 - 1/g}}\ dx$$for constant k, b, \sigma, y, and g, eliminate all constants and ask about$$\int\limits_{x=0}^\...

In a way literally nothing happens. You click "Add Comment" and the situation stays unchanged. The "too long by" flickers briefly, but that's it. As explained in a comment by amWhy there is a check on submission. I dimly recall that in the very early days this was handled much less gracefully, and the text in the comment box got cleared ...

A question can have more than one duplicate target. You can find some examples in this SEDE query. As far as I remember: This happens if various users choose various duplicate targets when voting to close. And also if the list of duplicates is subsequently edited - this can be done by moderators or by user with a gold badge in the specific tag. So to ...

It's possible to analyze this with help of the Stack Exchange Data Explorer if you know a bit of SQL. The procedure is as follows: Split the body of the post into several chunks, splitting on the \ character Check which alphabetical characters appear at the beginning of each chunk Luckily, all posts starts with <p> so the first chunk, which is not a ...

First and foremost: You are not alone feeling/thinking that on some occasions you would prefer only to cast an ordinary vote! I don't think you can forsake the superpowers, but you can use them responsibly. I don't think there are any normative guidelines for this. Instead I list a few thoughts I recall having, and practices I have tried to implement. ...

No, this is not possible. See e.g. this post on Meta Stack Exchange: Is there a way to see who voted on your posts? No, voting is by design anonymous. Not even ♦ moderators have access to information on individual votes. Knowing who up- or downvoted your post would likely incite some users to up- resp. downvote the voters' posts, which we want to avoid: ...

As already mentioned in comments, SEDE can be used for such queries. I took the query showing the users with most bounties awarded and I have sorted it based pm percentage of the reputation given away in bounties: Highest percentage of reputation offered as bounties. One problem with the query is that all suspended users are in the database with reputation 1....

The \substack command allows one to stack several lines under (and over) an operator symbol like $\sum$, $\prod$ etc. The argument is enclosed in braces, and lines are separated by a double backslash. For example \sum_{\substack{k = 1 \\ k \neq \lfloor n/2\rfloor}}^{n} x_k produces $$\sum_{\substack{k = 1 \\ k \neq \lfloor n/2\rfloor}}^{n} x_k$$ where two ...

Is this a serial reporter or is this a general problem with my questions? I do not know if a serial flagger caused this, but in my opinion there is a general problem with your (closed) questions: I checked some of your closed questions and you do not explain enough what you have tried to solve the problem. In some examples you only posted the problem ...

While there are certainly different philosophies about what is the most aesthetic typesetting layout, MathJax attempts to reproduce as closely as it can the results that you would get from actual $\rm\LaTeX$. It is certainly imperfect in that, but the measure of what is "correct" for MathJax output (on $\rm\LaTeX$ input) is actual $\rm\LaTeX$ ...

Just added today... the "follow" feature.

Do not create a new account. If caught, the new account will be deleted, and the old one will be suspended. We do not take it lightly when people try to circumvent the automatic limitations of the software by creating more accounts. Moreover, one trend that you notice almost right away after becoming a moderator, is that the people who do create more ...

As a matter of fact you have asked 6 questions. That some of them are deleted is not relevant for the rate limit. It is also not relevant that they are similar; the system that enforces the rate limit is not that advanced to begin with, and even if it were, the behavior is undesirable and thus to be discouraged. The only viable solution is to wait a few ...

Your deleted questions are very much counted just as much as the undeleted ones.

There is a list of domains which might be necessary when browsing or participating Stack Exchange on Meta Stack Exchange. Perhaps you're missing ajax.googleapis.com or cdnjs.cloudflare.com? I have uBlock Origin installed, and AFAIK it tells you all domains which are being used for a page. For chat, it's the following list: stackexchange.com chat....

No, this is not possible. This will happen in only very severe cases (think links to child porn) and often those are redacted and not hard-deleted. By posting content on Stack Exchange, you've agreed to the Terms of Service which state the following: Subscriber Content You agree that any and all content, including without limitation any and all text, ...

One lazy fix is to use phantoms: Expanding the decimal expansions lines things up: \begin{align} 124\phantom{.000}& \\ \underline{+\quad 53.258}& \\ 177\phantom{.000}& \end{align} \begin{align} 124\phantom{.000}& \\ \underline{+\quad 53.258}& \\ 177\phantom{.000}& \end{align} A more correct way is to put the & (alignment) ...

Technically it was not a change of the name. What happened is that I recently switched the direction of the synonym between pde and partial-differential-equations. It used to be the case that a questions to be tagged partial-differential-equations was automatically retagged as pde. Now it is the other way round. As Martin mentioned that's discussed at ...
