I was reading about this a while back, and I tried out the tour of it on the site and I like it. But alas, it's not really released to everyone yet and I don't have one. But I did change my email address, I'm using a different one now. The other one got filled up too quickly everyday, I couldn't keep track with it. Are you still able to send invites? If so my email address is firstname.lastname@example.org if you would be able to send me one please?
