I imagine that it's actually a deliberate design decision to prevent people who won't use the Q&A function of the site from being able to use the stackexchange network as a chat server.

The commands \lbrack and \rbrack are macros that produce [ and ] respectively, and MathJax has no problem when you use them instead of the symbols - see the comment below, which was produced by For any $a,b\in \lbrack 0,x)$: $a\vee b$ exists. Namely, $a\vee b=\max\{a,b\}$. You might be asking about when directed sets are [complete](http://en.wikipedia.org/...

At this time, I will have to decline this. In the last 90 days, there have been 10 migrations to Mathematica (with a 30% rejection rate), and 2 to Computational Science (with a 50% rejection rate). As noted by Mad Scientist in the comments, we only open migration paths to new sites when there's a demonstrated need for the migration path due to high ...

This is a known issue, and a won't fix (or rather by-design) I believe. See here: Old usernames stick to Community Wiki posts Basically, they store the name which was, at that moment in time.

I don't really relish being the bearer of bad news, but here's a recent answer by Shog9 on Meta Stack Exchange: This request was discussed by the team on April 9th, 2014. The potential rendering cost would be such that it would need to be a per-room and per-user option; this would then create a situation where users would potentially never be sure how ...

I strongly hold the opinion that websites should not enforce their own idea of browsing on the user. Let the user browse how he wants, and let his browser handle the browsing. In particular, any user who wants to open a link in a new tab can do so easily using the functionality of his browser.

It has already been pointed out in the comment that a similar suggestion from 2009 was declined. That said, I disagree with the proposal because I believe that should be handled in the browser. I would be (very) annoyed if I would get a new tab/windows every time I clicked an external link. As it is now I can navigate links exclusively using the mouse and ...

I'm writing this answer to provide both a target of upvotes for people who would like to see this migration option and a space where we can collect questions that would have been appropriate for the Mathematica site. I agree with Asaf's comment under Grace's answer (which received more upvotes than the answer by the way); we need statistics on what actually ...

False alarm: caused by chrome extension I should have checked before what happens when I turn off all my extensions (or log into chrome from a different user). It turns out the culprit was an obscure Chrome extension I had installed called "Emoji Input by EmojiStuff.com" that was supposed to allow viewing certain emoji characters that I couldn't otherwise ...

That's not a bug on our side. I've submitted the URL for review here: If this bothers you, I suggest you do the same.

The mini-markdown in the comments is different from the full-blown markdown in the answer and it's optimized for efficiency even though this means we can't support all the features of normal markdown. Please adopt a workaround if it is possible.

As mentioned by Theo and Hendrik in the comments, the problem is that sometimes the edit and delete buttons get hidden behind other elements on the displayed page, making them inaccessible. I describe a slightly convoluted, but often working way to again access those buttons in this answer.

In most cases, you can just click on the offending line and highlight it towards the right to scroll to the right. I don't think that it would be good to break long formulas arbitrarily. So taking into account Theo's comment, I fully support the request for the shift of the delete sign to the next line.

I can't reproduce this in other browsers, so my money's on IE11 doing something funky. It's just about at the tail end of its life and the issue looks to be fairly minor, so we're not going to be addressing it at this time.

There are ways to make invisible close brackets. \vphantom] will usually do the trick, I imagine, as the previous open bracket will have made the line the same height this otherwise would. If you're desperate, \smash{\vphantom]} might work in a few more cases. There may be stronger ways I don't know about.

When MathJax fonts are defined to be a color, but are displayed in black, this almost certainly means you are receiving image fonts (rather than web-fonts). As a first resort you should clear the browser cache and try again. After that, some things to check are: Are you behind a proxy that rejects OTF web-fonts? Have you installed STIX or MathJax fonts ...

Can't reproduce this in Firefox 5 (current version) on Windows 7, so it is likely a bug specific to your OS or Firefox, not our site.
