I have 6 Gmail invitations (from Google, with 1000MB of storage). I've been using it to archive my mail for the past couple of weeks and am surprised with how fast it is. They're still supposedly testing the system so haven't opened it up for anyone to sign up yet. I got my invitation from ChicagoFreeCycle.Org so plan to give 4 of the invites back to that community. The other 2 I'll give to anyone reading here that would like one and posts in the comments here, no strings attached, but it'd be great if you'd tell us what you're most passionate about, especially related to personal and/or social change. Thanks!
