I don't have a date in mind, but, would anyone be interested in meeting in Vegas (or some place else) to be able to put faces with screen names? I'm thinking small, nothing that would require paying additional fees on top of travel in order to rent conference space. Also, I think the date should be picked for far enough in advance that everyone has a chance to properly plan their finances and schedules (like, some time next year).
I suggest Vegas because there is enough to do there that if, for whatever reason, you don't like hanging out with the members in person you will have plenty of other things to do. Plus, Vegas is fun and travel packages tend to be affordable.
