You're not getting logged in for some reason. Contact the Administrator or post a message "MACON, HELP" Hopefully, he'll see that and contact you. He can reset your username. Or I think you can register under a new name.
Try clicking on the Logout tab at the top of the page and logging in again. Should solve the problem. If not email me at [email protected] and explain the problem and I'll try to fix it.
Most of these type login problems are caused by logging in on a computer at school or office and not logging off. When you login on your home computer the server gets confused and can't figure out if you are logged in or not.
