When we had the last few people leave the board they thought it'd be a good idea to erase all their posts. I understand that they felt like it was their intellectual property, but they were intentionally damaging the boards at the same time. So unfortunatly, for the sake of the board, deleting posts has been disabled. If their is something that any member sincerely wishes to have removed then report it to the moderator with a message describing your situation.
