I think I found a bug. What should I do?

First, if you feel your bug is a security issue, in SME Server or in the contribs.org website, please send an email to security@lists.contribs.org. Otherwise, please check the Bug reporting and confirmation forum here to see if it has already been reported. If your bug is not listed yet, you might open a thread there, to gather any pertinent feedback. If it is accepted as an actual bug, someone will open an item in the Bug Tracker tool, or suggest that you do.
