Not a big fan of the logo. It seems....squished down. I would say lose the glow and give the lettering a bit more height. You will also want to create brand recognition at this point...the colored letters are a good start.

From the logo I am getting the impression that this is a general chat forum. However I think you have too many forums for the amount of traffic you currently have, it makes everything look empty. Merge similar topics to start, then add more forums as the community requires it.

The icons and colors are generic and should be updated to reflect the unique nature of your site.

You are trying to enter into a quite saturated marked (General discussion/Technology Discussion). You will want to focus on what makes your community worth joining, and make sure visitors know this.
