ContribHub
ContribHub was born on 2012 at PulsoConf/BogotaConf hackathon after 14 hours of sleep-deprived programming, with the goal of creating a good tool to help other open source lovers to find projects to contribute.
There is still a lot of work to do, but these are the core features: Submit your repo as "Help Wanted" Search repos by your personal interests and useful filters Find projects needing help or people "near you" doing cool stuff Contribute, collaborate.
