If you have a question about how to do something, please open an issue on stackoverflow; please tag the question with "backdraft".
If you've found a bug, please open an issue in the Backdraft repository. Your chances of getting attention are much higher if you provide a reproducible test case.
Request for Enhancements
You may also request an enhancement by opening an issue. Again, your chances of getting that enhancement incorporated into future releases are much higher if you provide a pull request with a test.
