They're like love: The more you give away, the more you get. Here's the run-down for those who don't know:
Gmail is google's email. They are only allowing people to join with an invitation, probably to keep out spammers. It is unlike any other email account I've ever had... and I've had plenty. For starters, they give you 1GB (1000MB) of storage, and instead of deleting emails, you can archive those you might want to refer to in the future... then use google's search mechanism to find that great recipe or whatever later on. It's awesome!
If you'd like an invitation, I'll need your current email address (to send it to), as well as your first and last name, so you may prefer to email me rather than leave that information here in the comments. I promise, I will not use any of your information for any purpose other than to issue the invitation!
