ive made a couple trades on this site. it works. the dev is making improvements too. I did have an issue when i first used it but the dev fixed it. I had my doubts too untill the dev fixed my issues after he got my email. He also addressed the issue on the forum.
Their support seems quite responsive. At the moment theres not a lot of trade going on there however I'm sure thats because the sites new and people are wary. Once they have been around a while trades & volume will pick up.
Will be following this project with interest. Nice to have someone as talented as you here.
