I don't know how many people here are interested but I know there is a lot of interest on other sites.
I have 15 Google Wave invites that I'm willing to give out. The first 15 people to PM me their email address will get an invite.
NOTE: The invites are processed once a week by Google. Any invites I send out won't arrive to you until sometime this weekend (maybe even next Monday). Please be sure that you do not make a mistake when typing your email address out to me. I only have 15 invites to give away.
