An eBay style system makes a lot of sense to me, although it could be improved upon (I've always thought the developers at eBay were on the lazy side -- either that, or the ranking had to be dumbed down for their target demographic). It would be nice to know -- in a glance -- how many domains have been bought and sold via DNForum successfully by each member, as well as some other stats, such as the average buy/sale price (to indicate possible budget) as well as any negative marks.
I know this is a lot of info, and some members may not want other members knowing their range, so this will probably get shot down in committee. Several options to make these kinds of stats more palatable might be restricting this information to Platinum members only, or allowing members to hide this info unless requested from a potential buyer/seller.
Yeah, this is getting kind of complicated. Maybe the simple eBay way is easier after all.
