Elliott,
Unfortunately I cannot provide a list for privacy reasons, but if you post something, i.e. "Who's attending Summit 2013? Want to plan a Community Meet Up?" I can highlight it, and it will stay at the top of the discussion board for 24 hours on Monday. (This is a new sticky feature in Community) Maybe you'd get some activity around it! I think it's a great idea and could educate those that don't know what value the Community provides. 🙂
