I think he is referring to the Jekyll & Hyde thing. On one hand I have a heck of a sense of humor and can be quite jovial and easy going, until the forum rules get violated. Then I turn into your worst nightmare. Violate them over the weekend, when we are closed, and I will be a complete arse about it.
It is pretty simple really. I give what I get. Show the forums and people no respect and expect none to come back at you.
