On another car forum I'm on you have an etrader icon below there name when they post that shows how many people have written a review for them. The purpose is for when people are selling things. Buyer can leave feedback and the seller can leave feed back. The comments cannot deleted except by the person who left them.

Kind of similar to ebay in the way you can leave a neutral, postive, or negative feed back. I recently had some bad experienced trying to buy something off a member here and without publicly bashing them; It would be nice to avoid that in the future.

for reference it's gtrcanada.com if you need to see what forum they use.
