This was all fixed up thanks to ctrl-alt-delete and his wife before I had a chance to get involved, but reportedly the hacker(s) wedged a series of pro-Syrian Army propaganda into the top section of the forums.

I don't have confirmation on who was responsible, but comparing the similarity of this attack to others that have hit other websites in recent days, I would say the http://en.wikipedia.org/wiki/Syrian_Electronic_Army is a good bet.
