I got my firstinvite about 2 months ago, since then I have to admit that I haven't used it that much nor have I really been overly interested in its capabilities. However , I do have a quantity of "invites" (it seems that you receive them every month to add more friends!) but as I'm a social reject! I don't seem to have many people "connected" in the wave.
So if you have a desire to get into "THE WAVE" then drop me an email and I'll pass off these invites that are doing nothing!
