Please enable the AMSsymbols extensionfor MathJax. The lack of this extension has led to several independent bug reports.

More independent bug reports (everyone, please feel free to add them if/when you can edit this post):

  • $\begingroup$ The fourth link you included is to a thread on the 404 error page, is that what you meant to do? $\endgroup$ Nov 14, 2010 at 21:48
  • $\begingroup$ Dear Carl, you do know that \Rightarrow (or one of its lengthened varieties) gives \implies, right? $\endgroup$

  • $\begingroup$ @Willie: I was the one who made that post. I had wanted to use the $\nexists$ symbol, which renders slightly better than $\not\exists$. KennyTM helpfully edited my post to fix it, but that means one has to link to the revision history to see evidence of the problem. $\endgroup$

    $\begingroup$ @97832123: actually I ran into this problem with the Hebrew letter beth. For random newcomers, having the macros available would be the easiest solution. $\endgroup$ Nov 15, 2010 at 4:57
  • $\begingroup$ @KennyTM: why did you remove the "bug" tag from this post? It's clearly a bug - the symbols that numerous people expect to work don't work. Apart from that - is there any specific tag that flags the post to get the attention of the people who can activate the extension? $\endgroup$ Nov 15, 2010 at 18:09

    $\begingroup$ @Carl: A bug is some wrong outcome that is not what the designer expected, therefore they can be denied by [status-bydesign]. So far this is clearly by-design as extensions are not turned on before we request it. A feature-request is some desired outcome that (most of) you want to be. A feature-request doesn't mean it is less important than a bug. $\endgroup$

  • $\begingroup$ @Carl: The [tex] tag should be sufficient. $\endgroup$

    $\begingroup$ Can we get a timeline on a response to this? Recently I've been rather discouraged by the response of site administrators: from my perspective, it seems that almost all of their intervention has been negative. (I was especially distressed by the locking of a thread that detailed a very reasonable complaint.) This should be an easy opportunity to improve morale... $\endgroup$ Nov 16, 2010 at 1:25

    $\begingroup$ @KennyTM: "A feature-request doesn't mean it is less important than a bug." Perhaps not, but I'm pretty sure it gets less priority than a bug. $\endgroup$

    $\begingroup$ @Rahul: One's priority does not affect the nature of the issue. $\endgroup$

    $\begingroup$ @KennyTM: Fair enough. I still feel ought to be a distinction between the "It would be nice if I had a pony"-style feature requests, and "The product is working as designed, but there is something wrong with the design " issues. I would consider that sort of thing a bug in the very design. But there's no way to express that, so I suppose [feature-request] will have to do. $\endgroup$

We have enabled the AMSsymbols extension - this will be deployed with our build later today.
