It should be official, I've been talking with them through email the past couple days using the email they provided on the page. I've talked specifically with Andrew Hill.
There is talk of a Reddit AMA with Workshop Artists that was being put together in this thread. It would be a great opportunity to not only talk about the work that we do but also discuss some of the issues with the Workshop as a whole. There is a Google Doc in that thread if you want to register your interest.
