Shuba,
Great ideas -- this is lots of information to gather for this congregation! Along the way, as I think you intend, you'll also hear the narratives of these people -- why they came to be part of this congregation, what they think is important here, the history that has shaped them. This is the "social awareness" part of the EI work we'll be doing -- and I think it will be very helpful as you work towards shaping whatever the future holds here.
