Thanks to some timely and clever help from my friend Joseph, the forums are back up!
We had to uninstall the old forum plugin and install a new one, but we were able to access the old posts and repost them in the new forums. (That’s why all the old posts are dated today and have “admin” as the author.)
If you registered with the site in the past, your login should still be the same. Of course, drop us a note if you have any problems.
