-I'd like a 'view all posts from this ip/subnet/username' option in the admin panel if that's possible. I know we talked about it and static pages, etc. but it's worth an asking, I suppose.
-Scaleable administration (ie, mod status and admin status with different permissions)
-Forcenick and/or force anon for one user
-Maybe word filters? Kinda silly but sometimes fun. If you do it, make sure to allow html injection in the filtered text, because what if someone wants to make it a picture?

I'm sure I'll come up with other stuff, which you can also feel free to ignore.
