i like the idea of teaching, thats sort of exp sharing.
i mean, say u know alot about crafting, and soem other player has a high *learning* level, then you could easly *teach* him about three crafting levels.
this will be done for a agreed fee, and for a certain time which will be displayed when the *trade* is made
its a good idea in general, but who\'s to stop the players to teach themselfs stuff for free, all night long ?
if dev people come up with a solution for that, all will be good.
