There are a few things about the community site that I wish were a little more cohesive and modern-looking, and I think could be easily changed.

The colors used on the forums don't match the rest of the site well. Specifically, message and edit boxes. They're too bright, compared to the rest of the site's relatively dark color scheme! It's almost blinding on a bright monitor.

The wiki could also make use of the Vector theme, recently added as the default to MediaWiki. It's a very nicely done theme, and it would be very easy to put the game branding on it.
