With the way these boards are integrated into the whole site, there's no obvious way to add a  signature, add an avatar, etc.  There is, however, a secret way to do it, lol.

If you have at least 25 posts and have been a member for at least two weeks, feel free to send me an email at admin (at) divatribe.com and I'll let you know how you can go about putting up an avatar, etc.
