Logging into the ticket system

At present, the ticket system is integrated with the Fedora account system. Use the the Fedora accounts system usename and password to login. If you currently do not have an account, check out the instructions at http://fedoraproject.org/wiki/Infrastructure/AccountSystem . Anyone who is already accepted as a user in Fedora can request an account through the Accounts / Security / Passwords section in the ticket request. The only requirement is that users be sponsored in the group they would like to monitor. To retry the login goto https://admin.fedoraproject.org/tickets/index.pl .
