ATLRUG.org design help requested...

Ok so as you can see, this is a pretty vanilla site.  We must have lots of creative types in the group.  Is anyone willing to help with the style?  Also, would it be helpful to have a special code for users to enter on registration to deter spammers?  Code could be given out at meetings, or retrieved from irc, or another member.  I dont have any anti-spam measures in place yet...
