***IMPORTANT NOTICE***
Going forward, logins to the AVSIM forum system will no longer accept the user's display name as a login credential. Please instead use the e-mail address registered on the account.
Note that if you have your login credentials stored in your browser, you'll need to clear it's cache and possibly any AVSIM-related cookies. Otherwise your browser will be automatically sending outdated credentials to the server, resulting in failed login attempts.
