friend system?
post count?
better text box for easier rping. (where you press a button and it does the bbcode for you. on the old site I used it all the time. it was pretty awesome)
PM alert? (tell you when you have a new pm to read. great job mahz with the threaded PMS!)
more tabs for the roleplays (IC, OOC, Character sheets, interest checks) 

sorry for the lazy typing I'm on a phone and at work but I just wanted to throw out some impovments I'd like to see for this site.
