Hi, Deborah requested more information on Ravelry, so here is it:
Kind of like Myspace, but not (eloquent, isn't it). And, it's just for knitters.
On ravelry you can blog, post pictures, post on forums, basically anything you can think of and any way you can think of sharing information about yarn, knitting, and crocheting. Everyone has a screen name and their own page where they can post their newest project, show off their stash (which is scary, and it's a good thing I left most of it in the US), and join groups (That Yarn Store has one).
They have a preview for you to look at: http://www.ravelry.com/tour/video/preview
The waiting list is pretty long, over six thousand people at the moment. Once you sign up they'll email you in a few weeks (or longer?) and let you have an account.
It's still in beta, which is why they have a waiting list as they probably don't know yet if they could handle all the thousands of people on the site at once. I haven't run across any bugs yet though.
