He has a website www.enviromintcoins.com I believe. You can read about his operation as well as find contact info there. I've sold him some scrap gold and agree that he's fair and easy to deal with.
His last post was May 5, last active May 7th, he doesn't post a lot, maybe couple times a month with breaks but he is around and I personally feel he is trustworthy.......
I would contact him through his email which is on his profile or his website which also has email and phone number..............
