For those of you with Gmail, you have probably noticed that there is a "Invite a Friend" link on the left side of your screen that allows you to send invitations to two people to get Gmail.
These are the invitations some are selling on eBay for around $40 each.
If you don't have Gmail and want it, see if you can talk a Blogger user into sending you one of theirs.
For those who still have invitations available, pick a couple of good friends and make the day for them.
Don't sell your invitations on eBay. That's just plain tacky.
