I understand the joy of being a Chair and trying to figure out what works for everybody.
I think we probably have to stick to the two-hour increments, for a couple of reasons. One is the technical aspects of scheduling, but also, two-hour increments are what other committees have, so if we start overlapping into other committees, it would make it that much more difficult for our members to schedule and to be able to attend.
Our preference is probably for two two-hour meetings, if there is a way. We're not adamantly opposed to the one three-hour meeting, but I think it's that much more difficult to plan.
