I’ve had a Gmail account since early July (I was able to get it from an old Blogger account I had) and haven’t received any invites until the past couple weeks. I initially had 5 to offer and gave away two or three of them. Now it keeps getting bumped up. Whenever I give out an invite, I seem to get a few more. I wonder if Google is being more generous with their invites in preparation for a public Gmail launch (it’s been in beta since April).
If you or anyone you know would like an invite, I’ve still got a few to give away. Just let me know.
