Taking a cut is good, a la NCT sales. But only poss if a fee is charged.
A post count would be very, very useful, lots of forums have them. So name changers get an instant short shrift if they are selling. (unless everyone knows them anyway)
I still think it ought to be self policing...if we only use the boards to buy and sell with FRIENDS on here, ie regular and recognised posters.it's unlikely anything can go too wrong iyswim...it isn't MN's fault if people buy from someone assuming they are Ok without actually knowing them as a regular poster, is it? The whole point is that we are buying from mates I thought. Otherwise may as well use ebay.
