I finally got my invite to Ravelry about a week ago and I'm impressed so far. The way you can link everything together and see who's working on what project. I like how I can see which of my patterns are someone's favorite or see photos of WIPs. And the group thing - I keep finding ones that I like so I'm in like 25 groups. Is it possible to be in too many? Anyway, I think this is a great community project.
