The most important part of your question is not if we would allow it. The most important, and first question to make, is: "Would your university allow this kind of thing?". We cannot answer that, and that is something you must come in to terms with the relevant departments. If/when that is out of the way, then there is a lot of issues with this approach, ...

You can have as many accounts as you'd like. But they must act as one. In particular, what you wouldn't do with one account, you shouldn't do with the other. It's not that it's against the rules as much as it is a type of self promotion that is not great. So overall, please don't do that.

From a sample of several of these accounts, they do all appear to be the same user, who has not registered an account and seems to clear their cookies between each visit to the site. It would make sense to merge them. However, moderators can no longer merge users; it must be done either by the user themselves or the StackExchange team. Since there does not ...

Looking at the UserId is a serious overestimate. The query SELECT COUNT(Id) AS NumberOfUsers FROM Users returns 82335, based on the data from October 13. (This includes both registered and unregistered accounts.) Since September 1, new users are joining at the rate of about 180/day, see new users per day. If this continues, the user base will reach 100000 ...

CC licenses prior to Version 4.0 also require you to provide the title of the material if supplied, and may have other slight differences. (copyright, license and ...

From the top of my head: Ilmari Karonen is the maintainer of SOUP that patches various glitches on SE-sites, some specific to this site. See the user page for details. robjohn has developed a tool, known under the name CatChase ChatJax, so that math renders in chat. As far as I know it is widely used, and makes chat a lot more useful for some. See a meta ...

I challenge your assertion that "a great number of persons that have been created an account because they were motivated to learn and share mathematics". My guess is that a large majority of the people who create accounts on MSE do so in order to get a couple of homework questions answered right before a deadline. They don't care about maintaining a ...

The numbers are assigned consecutively to all accounts created on the site. With one exception, they are positive integers. The first accounts are created by SE developers in the process of putting the site together. Geoff Dalgas is user number 2, and there is no user number 1 (I don't know why). The first "real" (non-SE-affiliated) user of Math.SE was Noah ...

It is allowed to have several accounts as long as you do nothing with those accounts that in essence you could not also do with a single one. Some examples of things not to do: Do not use a new account to evade a suspension or ban. Do not vote for posts of your other accounts. Best, try not interact with posts of your other accounts at all. Do not use ...

No, on a per user basis it's not a new record, not even close. See the point-timeline of Brian M. Scott around end of March this year for a recent loss an order of magnitude higher. Yes, for 'large' accounts votes are often preserved. Actually the criterion are the votes cast, not the points of the user, considering both the absolute number as well as the ...

It is no longer possible to ask questions with an unregistered account on Mathematics Stack Exchange. The change was made on or about 10 Oct 2016, at least in part in because of the response to the feature request Let's require registration to ask a question (see Grace Note's answer to that question). (Users can still answer questions without being ...

Yes. It's possible. People can open more than one account, and some people do. If both accounts have reached 3,000 points then both can vote to close. The SE software does its best to disallow a user to abuse the system in the form of two accounts acting simultaneously towards the same goal. If a user has voted twice to close a question, or voted twice for,...

There are some problems with this suggestion: (1) it makes sources of posts less readable (/portable); (2) what should happen when one user edits other user's post? (3) including a lot of command definitions in all user's posts certainly won't make processing of MathJax faster. Somehow this feature request reminds me of the Tower of Babel.

The help center contains a page with instructions for how to do it. Since you have significant contributions to the site, you contact Stack Exchange and request the deletion of your account. You will be told what further actions you need to perform to ascertain that it's really your intention to have your account deleted, and when those are done, your ...

We don't want users to delete their question after they have received an answer. This is because that deprives the answerer the chance to get the reputation bonus they deserve for their work. Somebody considered the question worth answering, and after that point the community should decide whether the question is worth keeping. This applies equally to the ...

Your question are recorded as long as they do not get deleted by votes of other users or a process to clean up badly received content (thanks to quid for making the point more clear). And even then, once you'll have more than 10k reputation you will be able to still see them (after deletion). However, you will not to be able access them so easily as the ...

Yes, it is permitted to keep different accounts for different communities. The only real rule about multiple accounts is that they cannot be used to give the impression of more than one person. For example, you can't vote with two accounts on the same question, have a conversation with yourself as if you are two unrelated people, use one account while ...

A brief answer is that you should go to your profile and click on the number of consecutive days. (Remember that you'll find this in the profile tab, not in the activity tab.) You can find more details here: Statistics of visits on M.SE Implementation date for the consecutive days calendar How can I see which days I visited site? The tag-info for the ...

To find posts by a deleted user if you have the userid you can use Data Explorer (SEDE). See also: Is there a way to check all questions/answers posted from a deleted account (MathOverflow Meta) and Shadow Wizard's answer to Why not keep anonymous profiles accessible? (Meta Stack Exchange). Some examples of SEDE queries: Get posts list of a deleted user ...
