for me it's the chocolate pudding and mental masturbation. I wish most of my friends were as smart as the guys on the OT board.
For technical, I shared the week-by-week build of my track car and TRY to share anything new I learn along the way. I TAKE much more than I give.
On classifieds, my role is ONLY to protect the innocent who may be taken by wily purchasers/sellers.
Actually, buying/selling is/was an addiction, and you get to meet a lot of guys in a whole other way, talk about their cars, build plans, etc.
through all of this, I've met a lot of fellow Pelicans nationwide in my travels or in theirs to my neighborhood.
In short, it's all about Community (but the chocolate pudding is nice too... just ask Wayne about it).
