I got my invite to Ravelry a couple weeks ago. It's awesome, seriously, I don't mean to brag, but if you're waiting for your invite, just know that it's well worth the wait!
They added a group section to it. I took the liberty of adding the NYC SNB to it, so if you're a member of the NYC SNB and you're on Ravelry already, join here. If you're not a member yet, check it out when you get on, and friend me, PassionKNITly!!
ETA: OMG! There's a Burning Man group on Ravelry!!!
