Review plz: http://soulgaming.info/ Blog needs some work, we know, but we're currently trying to get the forum active ^_^
You need a better design for your header. It looks a bit bland. I like the colors, a Web 2.0 style going on. I think you need to work on getting suitable content for your users to browse through to make them come back.
Well, I think your splash page doesn't fit with what your website looks like. Change the image to something else that endorses the colors you chose for your website. And choose a different font than the graffiti one. I really dig the image itself, but like I said choose a different font and just use different colors for the image. The main page header could use the image for your header too. The forum, needs to color correspond to your site as well. I suggest choosing colors you feel represent "soul" and then apply them to the layout. Hopefully these suggestions help a bit.
Your site is pretty awesome so far. I'd think maybe you could run a promotion like "limited time pay per posting" in a certain forum you wanna beef up.
