i like that we're not using xmb anymore. even though parts of phpbb seem to be designed pretty poorly, this is a good change because i didn't really like that xmb.
some things that could be nice:
:arrow: let users change their usernames whenever they want
ops: (there must be a setting to hook that up)
:arrow: turn on the html! at least in our signatures.
:arrow: rename this forum to something like "EVERYTHING!" and don't add any others, except the good-evil forum if those guys want that again
:arrow: this arrow is a handy-dandy emoticon
:arrow: add some pretty colour schemes
