Hello
Due to a significant increase in spam mail we have now implemented additional restriction on new user email registrations.

Registrations will now no longer be accepted from anyone using a @mail.com email address.
This site, and the server it is hosted on, has now implemented a blanket blacklist of the @mail.com domain.

Existing users who are using a @mail.com email address are unaffected unless they happen to forget their password and use the "forgot my password" facility. In which case, please contact the admin team and we will see what can be done.
