there's always got to be the first post.
This site is running on Drupal, a powerful blogging/community CMS platform. Part community blogging, part forum, it's scalable, if a site grows, yet simple to use to add events and talk about rock, opera and what lies between.

no embedding, ok, added that, Allowing image uploads can be a security risk. Drupal defaults to a locked down version, and this installation is further limited by the host -- for now. I have the blogs and forum enabled. There are some errors, but everything seems to work.
