If you have registered and are not able to login, it is most likely because you have not been approved by the administration yet. The system does not notify me of new registrants, and I don't check the board daily.
Please send me an email (administrator) through this board to let me know you have registered. This is primarily to avoid bots or spammers from automatically joining this board and making life miserable (or entertaining, depending on who you are...ahem...get a life).
Also, as a new registrant, your first three posts are required to be approved, so please be patient.
