"Users cannot change their questions" - I really should remember these things...
Anyway, the bottom bit above looks rubbish, try mentally inserting \n whereever there is a hyphen.
The last thing I can think of now is that it's important that the chat page doesn't become the main platform whereby help is obtained here. I think one of the nicest ideas of perlmonks is the way that the archive slowly builds up, and as the chat doesn't get archived, knowledge may be lost.
For this reason, and this reason only (I don't like the next idea much as I think it could give rise to /. type first posts and Everything1 type ENN camping), it may be an idea to have an ENN type nodelet on the chat page as well, just to remind people of the main site...umm, I hope you know what I mean..
