Matt was never a TD but he was a Supporting Vendor once. Unfortunately he was not able to maintain his business and so his section was removed. As per checking his last visit was a year ago so I am doubtful if he would reply to you. Also, SVs are not vetted so you still take a risk when availing of an SVs services.

We don't tell everyone everything so why A is not a TD or B or some other, there's a pretty good reason for it.
