Take it to PM
Most people do not like drama when their lives are peaceful. If you have a problem with another user for something completely unrelated to the boards, please keep it off site and on IMs. While it may be entertaining to some, it's just a headache to others (especially mods). If a topic becomes heated, try to contain it in the topic alone and put it out before it blows up (this usually means one of you will have to stop and ignore the other).

Better yet.
Take it to the Octagon!
