Did someone use this site to trade? Do someone knows more about this?
Confused. Why their domain name is on-sale?
Well then, I don't know where you encounter this site OP. Hope you aren't shilling it here to make rooms for advertisement.
The fact that their information isn't much available anywhere should be a reason not to used them.
One guy ask me to trade with him and to use that site...I'm not advertising, just asking if someone had also the same request!
