Yeah, that was my mistake. I'm really sorry. Too many spammers and an itchy trigger finger. I thought I undid everything that flagging as a spammer did though. Don't see a flag for mailbox though.
Completely undoing the spam flag requires an admin, of which Hando has been MIA for a long time and EvilDragon is quite busy and rarely stops in. If you've only got one message, it is from me apologizing for flagging you as a spammer so you can safely ignore it. In the meantime I will continue to do what I can to fix my mistake.
