If you are already a Member but find you can't Log In there are several reasons why this might be happening.
1) Are you putting in your correct USERNAME. This is not the '
Display Name', but the Username you entered when you originally joined.
2) Have you entered your correct PASSWORD? Passwords are
cAsE SeNsiTiVe (with no spaces) so make sure you have entered this correctly.
3) The Website may be temporarily not available (eg. for updating, backing up and other management reasons) .. in which case the whole website will be 'down' and you won't even be able to read this.
4) You have not accessed the FORUM for a period of 250 days. In this case, you will have to Register again.
