The forum in the product of an open-source software effort. It is called YaBB for "Yet another Bulletin Board". It can be found at

We basically take what they put out without modification under the theory that our efforts are best expended developing content for the site and not the underlying software. They have a new version that is about to be released. That version supports attachments, which should help some by allowing you to upload gifs, jpegs, and pdfs.
