As you all know, fst6 is ranked #2 in AG. So it makes sense that there would be a constant flow of comments in his messenger, except for a few hours when there's not as many users on. I've seen that it has been hours since he's had a post.
Also, I tried to post there, and I tried for half an hour before I gave up. I left it there, and went to watch t.v. while trying to get the post through. I'm not the only person who has had this problem. I think there's something wrong with his messenger.
