I'd be willing to help with the main page, web design I can do. Forums... not so much. If you want any help with banners, I'm here for that too, though I'll be more available after friday, most of my exams are this week (2 tomorrow, 1 wednesday and 2 thursday, argh!), so I'll be free if there's anything I can do to help.
For me, it'd be hard to attract members as I don't go to many forums where I know people who would be... acceptable members here, but I'm sure I could scout a few on Gaia.
As for the actual forum, I think an urban/grunge look (McJebus, I sound like my teacher) would be nice, reds, browns, greys etc. Or maybe sepia tones. I think a warm, neutral look would be nice, I think it would reflect the kind of community we have. Warm, loving, soft and so on.
Just a few thoughts. Who can tell I had a graphics lesson today?
