The project period goes from May 29 through August 11
May 29 to June 2: Group members contact one another and settle on a first meeting time and medium (skype, google hangouts, facetime). Meetings last roughly an hour, depending on group members, and follow a pretty consistent format of reporting goals and self assessing, followed by some debriefing with one another. You want to meet weekly if you can-- see if it can form a part of your regular routine-- but no less than bi-weekly, I think.
June 3 to June 8: Hold your first meeting.
June 9 to August 11: When you end precisely is up to you (you may decided to reconvene in the fall) and you might continue, but I've chose 8/11 nominally because it's a ten week stretched that ends just before the transition to school prep. This way, you have end point to work towards in your planning.
