Quite a long time ago, the password system was changed to a more secure passphrase system. Those with passwords as opposed to passphrases were permitted to log in, and when they did a warning was sent that they needed to change their password to a passphrase. Now, passwords are not being accepted at login, and only a passphrase is a valid means of logging in. Apparently many, many players ignored the password->passphrase warning, and can not log in since they never converted their password to a passphrase. So, the staff is getting a lot of mails.
