We will be hosted by the MIT Drupal Group in Cambridge in Building E51 - Tang Center (mapquest) in room E51-149 . Thanks again to Ed Carlevale for hosting us and to Susan MacPhee for securing this space.
Parking and Transportation:
After 3pm, there is an unattended MIT lot folks can use. It is Hayward Lot http://whereis.mit.edu/map-jpg?selection=P5&Parking=go
Lightning Talks
Everyone is welcome and encouraged to present for 10 minutes on a topic of their choosing. You may show off your Drupal site, ask some questions of the audience, give a module demonstration, share some marketing ideas for Drupal, and so on. Just keep it brief. No expertise or planning required - just do it.
Dinner
After the meetup, some of us will continue the conversation over dinner at MIT's Muddy Charles Pub. We will likely pre-order some pizza so it meets us there. We'll take a count about half way through the meeting.

Organic Groups and node access issues
Someone had an Organic Groups question and I just realized that nobody suggested rebuilding the node permissions. Sorry about that. I was fiddling with the projector settings at the time.
There's also the Devel Node Access module, which can be used to diagnose the problem that was described.
