Seems like Gmail is refilling my invites these days. I gave away a few and all of a sudden it was back up to 6 invites. I think they should just open it up. Anyway, if you'd like an invite, leave me an email address to send it to. This time, I'm also accepting requests from lurkers and friends-of-friends readers.
Note that if you post anonymously, it will be screened but I'll see it. Please introduce yourself if it is not obvious from the email address.
