title: Restricting rights on GitHub
body: <p>My team is currently using Gerrit as code review tool for our git repos. Now we want to move some of them to GitHub. I'm not expecting to have as fine grained control over the rights as would be the case with Gerrit.</p>
  
  <p>I would however like to restrict direct pushing onto master. People should first create a pull request and then have this merged by a colleague. These same people should be able to merge pull requests, so not giving them any rights on the repo is not an option.</p>
  
  <p>Is this possible somehow?</p>
