Gmail

I finally remembered my G-mail account information. I signed on and discovered I had 50 invites! I sent one to myself because I want it again so now I have 49. The problem is, I don't know that many people. What do you think I should do with them? Make people suck up to me? Sell them? MAke people apply for it like a scholarship with an essay and stuff? Any suggestions? Anybody want an invite?
