I need to know how to give someone a positive tader rating. I have bought something from a fellow member. I would just like to help his credibility in future trades of sales. Thanks in advance.

 

The way I always do it is by finding a post by the user you'd like to rate.

Then below his post count it should say "Trader Rating: x" (where "x" equals some number). Click the number and then you can click submit trader ratin.
