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 ...

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.

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.

I can offer the following piece of information about trying to tweak chatjax to work on the chat page. Usually sites enable Mathjax by using javascript in their global header, so having specific options for certain pages doesn't work well with this configuration. That is, trying to have chatjax work as specific option on the chat page would probably ...

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.
