Here is a pet peeve of mine that could be fixed. I get a good amount of PM traffic. If I respond to a PM I have to go in again and delete it, or go all the way down to the bottom of the page to delete the damn thing (I have like 200 per page). It would be so very nice if you could put the delete button at the top of the PM list. I would keep a lot of my shit from clogging your servers I got down to 1600 or so PMs left and it quickly climbed to 2500 or so. Nit picky, I know, but it would rock!
Also, if every time someone used the search function you could make it say "Hail Dr. Evil" that would be agreeable
