I'm not going to lie - I refreshed a few times to get this screen shot of mine:
Alternatively, you can click on the link further down on the front page and Casey has the Ravatars sorted by the order that the users joined Ravelry - this only includes the people whose Ravatars have the 2million file name, not every member. I first joined Ravelry during the early days in May 2007 right before graduating from law school (post here). Back then the site was still in beta and they were only sending out a invites in small groups at a time to manage the traffic. It took about a week from the time I signed up until I received my invitation, which was fairly quickly because shortly after that it the word spread like wildfire and the list was a few weeks long to get an invite. To think that just under 5 years later there are 2+ million of us out there (as of the time of this post, there are 2,023,634 people signed up).
Here's to the next 2,000,000 and beyond!!
