The invitations you will receive at record date - 2 weeks will not be for the hangout. It will just be an event. The hangout invitations will go out to those who RSVP "Yes" and possibly "Maybe" about 1 day before recording. If you use a Google calendar, it will automatically tie you a link to the hangout when it starts.
The first 5-10 minutes will be setup, and then we will record for no more than 60 minutes. The time constraint will be to save space on the hosting service, as well as to not try our listener's patience over much. At about 55 minutes in, we will start wrapping up.
If you are going to be a late arrival, let me know and I will save space for you.
