I always enjoyed reading your posts, even if they did sometimes break the rules -- you always had a certain level of energy and enthusiasm in your writing. I also know that at least in your forum related dealings, you would always do the right thing, and would always push for the right thing. I have no reason to doubt you were any different IRL.
