We've released a new version of our FoggyValley blog skin that now is compatible with Community Server 2.0 beta (build #51107). Once CS 2.0 is released, we will test the skin again, and make changes if necessary. The download URL and setup instructions can be found on the following page.
If you are using Community Server 1.1 you may be interested in the previous version of the FoggyValley skin.
