the current rating system doesn't prevent non-traders from giving ratings. a poll or survey with comments would be better, like the bizrate model, but that would require a separate huge database. also, once rated, one cannot rate again, so if u trade more than once with a particular user, u cannot rate higher or lower...but then again, i understand the purpose for limiting the # times one can rate, the honesty of 40000+ members can't be trusted.
so, it isn't a good system, but it isn't bad either...the perfect system would be too difficult to manage, since this is only a disscussion forum and not a trading site such as eday...
