1, make it so the forums are easier to use.
2, make barrows more realistic, like make the armor restraints correct (ranged levels for ranged armor), and make barrows brothers go on correct hills.
3, webclient, or fullscreen desktop client.
4, staff crowns next to name when a staff member ::yell's.
5, make it so that it doesn't say "Username has logged in." every time someone loggs in, because that will be realy annoying when there are like 100 players.
6, make it so there is a ::vote command, where it opens up a new internet window, and takes you to voting page.
Thats all for now.
EDIT FOR MORE:
7, make a safepk, or so that you don't lose items when you die in ::cw
