Yup we got hacked last night. I've fixed what I can but it's still showing on every thread on the site. Matt is going to try to write a program to remove it or we may be able to get a back up from our host that is say 24 hours or so old that we can replace and only lose a few posts but get rid of the war message.
Give us a little time and we'll try to get it back to normal.
In the mean time anyone can edit their own post if they started the thread to remove it. So can moderators on their forums. I'll delete some as I see them today.
Hopefully Matt will find a mass fix soon but until then members and moderators can help by deleting it with an edit.
