Mike, that's not a bad idea, and I've thought of perhaps trying something like that here, but then someone has to police it and assign credits... and that someone would have to be me... and if I'm going to take the time to do that, I might as well just answer the question. :)

I've always encouraged my customers/students to try to help out as much as possible. If you see a question and you'd like to add an answer to it, please be my guest. Right now, ALL of the questions posted are moderated because even with the captcha (the image of the word you have type in) I still get a TON of spammers trying to post garbage in my forums. So I try to go through at least two or three times a week and approve/answer questions.

But yes, I would be happy to give some kind of credit to users who help other users out by posting help/answers to questions. Perhaps points towards free classes or some such thing.
