We have now change how users have to login. Users will now have to login with their email address used to register and their password rather than using their username and password.
The change has come due to a number of spam attacks coming toward the forums where bots are attempting to login to peoples accounts and causing users to get logged out. The attacks are coming from new IPs each time meaning continuing to ban new incoming IPs is not an adequate solution, hence this change. These attacks have posed no security risk to our users currently, however they continue to be extremely annoying to many forum members.
