Am I using an ancient revision/version and should update before reporting a possibly fixed issue?
Am I using any modification to core or database that could cause this issue?
Is it clear which branch I am using? (3.3.5/6.x/other)
Did I include the revision of the core I am using?
Did I include the version of the database I am using?
Did I include the operating system I am using?
Did I include the steps to reproduce the problem?
Did I explain what is wrong and what is the expected behavior/output?
While it is not mandatory to use the example above, we recommend it. (Adapted from Google Code)
