I actually think this is a cool idea, Andrek. I think it would add immensely to the RP and would enable more accomplished players to \"pass-along\" their skills.
I don\'t see why one couldn\'t structure in a \"Fair Market Value\" system into this to help curb abuses.
I do understand some of the concern--this is a very free-market concept and such systems do not function well in the absence of a moral framework.
For example, if I were a member of a Guild (currently training but not there yet), I would still be delighted to spend time working with a Newbie to help him/her progress quicker. My hope would be they would want to follow in my footsteps, but hey it\'s a free world and I can\'t force him/her to do anything, right? If they didn\'t \"take up the cause,\" as it were, it\'s my own fault if I didn\'t get something in return for my efforts.
