Hi, Matt,
I agree with Az, but I also think it should be taken a step further. Frankly, I think that buying/selling tutorials should be a must for any new member, as I have suggested many times. One can "suggest" until they are blue in the face, but perhaps making it a required action might help just a little.
Also, if the tutorial is mandatory, then a buyer/seller cannot claim they did not know the rules, and therefore eBay could "crack down" with more force, since users should know better.
Another poster mentioned that there should be a tutorial for FB as well. Is there a way that a member can be required to complete a tutorial for leaving FB before the first one is left? Even if the FB being left may be positive, once the tutorial is completed, perhaps the member will remember the points made.
I also think that each tutorial should have a "quiz" at the end, simliar to the tutorial that Rob posted a bot back. It may help make certain points "stick" in users minds.
Of course, this will not mean a thing if a user is registered to defraud or cause trouble, but for those who want to use eBay for the reason it is here, it may help just a little.
