2) If you find a security bug, DO NOT submit an issue here. Please send an e-mail to firstname.lastname@example.org instead.
3) Do a small search on the issues tracker before submitting your issue to see if it was already reported / fixed.
4) When reporting an issue, include Rails, Devise and Warden versions. If you are getting exceptions, please include the full backtrace.
That's it! The more information you give, the easier it becomes for us to track it down and fix it. Ideally, you should provide an application that reproduces the error or a test case to Devise's suite.
