I have trouble going through such a long thread to see if someone is on there or not.
There must be a better way. I don't necessarily think adding a good trader / bad trader section to the wiki is the way to go though. I'll start a thread in the Forum Discussion for anyone interested in knocking it about.
I've tried on numerous occasions to get people here to sign up for Heatware.com as a way to gauge feedback. You could still do it even now if you wanted, and back date feedback from that thread.
I got a few people to do it, and I still think its far more elegant that that thread.... not to mention it crosses the barriers of this site and can be used anywhere.
I think I even suggested it be put in the rules (as a suggestion only) at one point... but nothing ever panned out. So, when compared to nothing, the Good Trader's List is a decent thread, but there already are much better ways to handle it... you just need to get people to use it.
