Ugh, jesus, not another pointless bulletin board... Uh, your logo is fine, and I can't even tell you made a customized skin.
But, more importantly, here's a general rule of bulletin boards: people do not come for the design - they come for the content. And unless there's one hell of a conversation going on, you're going to lose users regardless of what your logo or skin looks like. I'd suggest to focus on that first.
