Currently having issues with the forum. We're investigating it and hopefully it'll be back up soon.
Update: It might be a couple days before the forum comes back up. I don't want to open the forum back up until I can confirm what happened with our server admin. As far as I can tell, all the posts, etc are still there.
Update 2: Looks like spammers somehow were able to relay their junk mail through the forum. The plan now is to rebuild the forum and restore all the data. Hopefully I can get all that done over the weekend.
