Gmail Invites, Anyone?

Found out just recently that Gmail is slowly opening up its doors to the public. Gmail invitations used to be so hard to get that you have to be somebody or know a somebody to get one. They're so scarce, gmailswap.com was set up to facilitate exchange of Gmail invites from people who have them and people who'll do just about anything to get one.

So now what do I do with my 50 Gmail invites?
