Starting this morning, I've been unable to post new topics in the DF Spoilers, DF Books, or the Bar. That is, the New Topic button just isn't there.
I got on this morning and the New Topic button was there, so I was typing up a new topic in the Bar, but when I clicked Post, I got an error message saying that I didn't have permission to post there, or something to that effect. I refreshed and then went back to the Bar, and that's when I noticed that I don't have the New Topic button anymore...
EDIT: And I don't have the Reply button for threads in those forums, either.
