I'm officially part of ProGen3. The ProGen groups (1 and 2 so far), meet and collaborate online to discuss the chapters of Professional Genealogy. There are also readings, assignments and discussions on a monthly basis. (The chats might be weekly. I haven't figured that out yet.) The whole thing lasts 18 months.
I am completely insane for doing this. I'm just getting in to the groove of the NGS course and now I'm adding more to the plate. The original plan was to finish NGS, then sign up for a ProGen. I didn't realize one would be forming so quickly, but it did so here I am.
