Currently i use http://www.codaset.com/ for private repo. It's free but it can't free forever. Codaset is nice git repo and we can write blog , wiki in there. I want to use private repo for my private project. Not commercial nor big project. I also found www.projectlocker.com/ but user interface is so poor. So, I want to use like codaset or github repo, for free at leat 1 users and 100 MB git repo
