Hadn't thought that far ahead. I'm thinking somewhere between every 2-4 weeks. I think that'd be enough time to let [other time challenged] people read through a decent amount of material.

Re. duration, perhaps 1.5-2hrs? Not really sure, though. Maybe that's way too long, or perhaps we could go on for a lot longer!

Definitely evenings if a weekday; otherwise weekends. I work full time.
