... to join Gmail.
I recently received one myself and signed up. Finally, I can return the favor. I have five invitations that I can send out (I had six, but had to hook Joshua up ahead of time). Just let me know if you want one.
This will be a first-come, first-served basis, though I do reserve the right to reject anyone. What can I say? I love power.
Let me offer a warning first, though. Gmail is not all that its cracked up to be. I had heard grand experiences from Gmail users about how it would change the way that you use e-mail. In fact, its pedestal was so high that it almost had no chance. Granted, it does have some nice features which improve upon what you've come to expect from Yahoo! and the rest. But this is not world-shattering type of stuff, people; this is, "Oh, that's kind of cool, but this kind of just looks like Yahoo! Mail did four years ago" kind of stuff.
Of course, the 1GB feature does trump everything else, if you have a need for that sort of thing. Beware WAP users, as I have yet to find a tried and true provider of WAP access to my Gmail account (though here's one that looks pretty shady, if you're into that sort of thing). Google certainly doesn't offer one.
