would be a modification to stock, but all doable
as for other bennys..
i typically do:
-- custom avatar
-- ability to search forums
-- custom title color
-- custom title
-- special group image like
(although i modify postlist and viewmessages to NOT display them.. they make the lists looks bad)
-- image in sig
-- access to arcade (mod)
-- don't have to view ad islands (but this is a philosophy thingie)
prolly some more, but those are the highlights.
