If your user name or password is not working, it could be that your account was deleted when the forum was recently reconstructed. If you email an admin, PLEASE include your old user name! The emails strip off the sender and WE CAN'T DO ANYTHING FOR YOU IF YOU DON'T TELL US WHO YOU ARE. I have been getting a series of emails from an anonymous person asking for help, but if you don't tell me who you are in the email, no one can help you.
If your account was deleted recently, sign on with a new account. Unfortunately, there is no way to recover a deleted account or recover posts associated with an account.
