Orkut is giving away GMail invites. Orkut is an online community where you make freinds, share photo’s, discussion boards etc. Orkut itself works on Invitation i.e. you need an Orkut invitaion if you want to be part of Orkut. Gmail is under the Beta tag for more than a year.
I got my Gmail invite from Blogger and it was something great to have Gmail. But nowadays you can get an invite easily.
