Yep, it’s true google is rolling out some invitations for the people who invite and the ones who got invited by other, it’s happening right now, and I've 7 more to send, if you want one you may contact me on my twitter (my link is over there <—)

BTW: Google Wave tip by me, you can send the link of one of your wave taking the url you have right in your url bar at the moment you’re searching for a wave, try to be very specific and use personalized tag so you can’t find your unique wave and share to others without miss confusing.
