Why not do a "Flyertalk dining week?"

No, it doesn't have to be a DO (See Jen, I didn't use the word "DO") It can be Flyertalkers meet over a certain week in a number of cities, at a certain restaurant and just catch up and have a good time and talk miles and points.

So it could be a number of concurrent mini "gatherings." Or, if 12 or more people show up, DOS (DUCKS!)
