Diigo invites available

There is a new service in the market, called "Diigo". It's impressive. It is a social bookmarking site like Del.icio.us and many others like that but this has many more features then that. I will be writing a review of Diigo service shortly, but for now I have invites available to give out for Diigo. So if you are interested then put down a comment here along with your email address (anybody with a blog is preferred).
