update: still no plans to support signatures.
i'm still evaluating PMs though. while i won't work on them for quite some time, it's something i'm still somewhat i'm thinking about. there are definately some pros/cons to PMing via boards.
hm... i think if i provide an easy way to send mails via the board (and hide your email address if desired) and add an easy way to reply to mails, i could omit creating a seperate PM system.
...hm... that really sounds good
