This page has been reverted. Big thanks to Ethertank, who fixed it by
the time your message hit the mailing list, and is always vigilant for
such things, and is generally awesome!
To answer your question, some users have the privilege of being able
to revert a page to a previous revision. Unfortunately, I don't think
there's any easy way to find out which users those are. Posting
problematic pages to this list is as good as anything. Often, like in
this case, someone will have taken care of it already.
