title: github: "Link" a Private Repo to an Organization
body: <p>I have a github private repository, in which I have been working with a few other (private) collaborators. Let's call it <em>repo-a</em>.</p>
  
  <p>A client just added me to their Organization account. I need to essentially share my <em>repo-a</em> with other developers in that Organization. I am not sure whether "share" is the right term here; maybe I need to "copy"? How do I go about doing this?</p>
  
  <p>The more important issue that I hope someone can help is I don't want the Organization to see the history committed by my private collaborators. But, hopefully, I will be able to easily "push" the latest code in <em>repo-a</em> to the Organization (I am still planning to work privately with the <em>repo-a</em> collaborators). Is this reasonably possible?</p>
