just do a quick search,
you should find them..
There are many forums out there based on Perl CGI
JAVA etc and have totally colors, but all seem to be the same layout. I personally have not liked any forums.
here are two links plus you have this site!
http://www.codingforums.com http://www.jsworkshop.com/bb/ Another Link:
click on the info pop link on the bottom of the boards, they have sites listed that use their software.
I personally would just try to create your own and not follow anyone else. One thing I would offer that would make you unique is the ability to personalize the board in the user setings. I wish boards had that feature so I could set colors, fonts etc. People say that makes the site not the owners, but hey I like my colors!
That is just CSS stylesheets, not hard.
If you need help just say so, also this forum (JS and HTML) sees little traffic on weekends, that is why there was no major reponces.
