I just noticed that I had a ton of invites for Pownce, so if ya would like a Pownce invite leave me your email and I’ll throw one your way. There are pretty easy to come by now.
I’ve also got invites for a number of other services… Yahoo Mash, GrandCentral, and Jaiku are the ones I can think of off the top of my head. Let me know if you want something else, chances are I’ll have and invite or know where you can find one.
