udmasterG what you need to do is come up with an original idea that separates your site from other sites. First may I suggest not letting your members build your forums, if you were serious about your forums in the first place you would have planned out what your forums will have to offer, it sounds to me as if you just created it because you were bored. Especially since your first couple of members to your site could be complete idiots.
At least get a skin I mean come on, try this
they have all sorts of skins and useful codes you could add to your forums to make them more interesting. Also you should work on some rules and board guidelines.
