Hey all - would really love to get some HN users into one of these groups. I've been doing direct invites of HN users for a while and it's gone well - I figured it would be nice to open registration up a little bit. I submitted here a few days ago and didn't get any response, but still a handful of new users - so here I am again. My goal with the project at this point is to try to connect people in slightly different ways than we're used to.
