Fixed. I applied to Google, but I got invited by a friend. To elaborate on Kane: People that get Wave due to Google accepting their application get 10 NOMINATIONS to share with friends. You are not guaranteed a spot. Google still has to approve your nomination before sending the invite. They may deny it to limit users. If you gain an invite due to a nomination, you may not nominate other users.
I HAVE WAAAVE. teamger@googlewave.com Now it's annoying to have this email as my Wave address... but well. Legacy.
