Clubs and Looking for Group are being made available to Preview members. According to the blog post, "Reserve your Club name today as no two can be the same!" I stopped being a Preview member a while back so I don't have access but someone should create a Club for duders from this community.
If one of you creates it, please post info here about joining. I'm sure others would like to join as well and maybe discuss early impressions of how well (or poorly) it works compared to just sharing gamertags here.
