Maybe something low key, possibly meeting at a cafe, somewhere centrally located? I think the place could be chosen according to who plans to attend (due to distance). How does January or February sound? Any interest in socializing, as well as (possibly) planning something for Darwin Day?
If someone is a member of the Burlington Atheists and Humanist group, and would like to talk this up over there once we've got a date, time, and place, that would be great.
Folks who are uncomfortable in social situations shouldn't feel like they'll be less a part of this group if they don't show up. However, RSVPs from those who are likely to come would be good.
If people want to start tossing out possible dates and places, that would be great.
