We're on facebook: http://www.facebook.com/group.php?gid=142511070752&ref=mf
And I've sent out an email for mass circulation, so circulate away! The best way to participate, we're discovering, is to have a party or gathering and make squares together! For more info on making a square, see the post "How To Make a Square". GO NUTS! The whole point is to get as many people involved as possible-- so show your square to everyone! Tell them what you're making it for and why. And if you email us a picture, we'll put it on the blog!
