ITrader, how do I use it?

[Roddd]

I'm on my iPhone, no access to a computer. I'm on the mobile version of the site, not the tapatalk app. How do I post a positive iTrader rating for a user? I had an excellent transaction with user comfortechinc, and can't figure it out. Any help would be much appreciated.

I go to the bottom of the page, and click full site. It takes a little longer to load. But it's much more familiar for me. I am not a fan of mobile site's because so much content is lost
