Sounds like a great idea... why don't we take a look at the due dates thread that's stickied & pick a couple possible people...maybe we could pair up everyone with edd of the 1st - 6th with people from the 14th - 20th, and peeps from the 7th - 13th with those from the 21st - 31st...
We could probably do a couple people each in case someone delivers early & their buddy is late...I don't know about you all, but I've decided that I'm going to be 1 week early, same as ds1 was. 'Cause you know I get to decide and all... :LOL
Seriously though, we probably have a couple weeks before we need to have our #'s exchanged, so hopefully everyone will post here and join in.

eta: well, those dates won't work all that well since more people are due the last week and a half then any other space, but ya know -- something like that! :LOL
