Including you, I've heard from 4 people saying that they are interested.  If anyone else is interested, or has comments, please let me know or respond to the list.  We'll only plan this if the interest level justifies it.

Yeah, two days of S/DC Train the Trainer workshop would extend the total GCC2016 Experience™ to 7 days.  However, I don't see a way around it.  Their training is two days long and I think it's pretty packed.  And I don't think that overlapping with either the Training Days or the Hackathons would be a good idea because of significant participation overlap.
