title: Add Github fork to existing repository
body: <p>I setup an Octopress project following the given instructions (http://octopress.org/docs/setup/) which have you create a Github repository, and create a local repository on your machine. On your local machine you add a remote to the original Octopress repository and then issue a "git pull" command. Then you add a remote to your Github repository so you can push your changes to your repository.</p>
  
  <p>All of this works as far as it goes, but it doesn't create a fork of the original project, meaning there's no obvious (to a newbie) way to issue a pull request to the original Octopress repository.</p>
  
  <p>Is there a way for me to add a fork of the original Octopress repository to my instance of that repository on Github? </p>
  
  <p>If there isn't a way, can I safely delete my Github instance of Octopress, fork the original on Github, and then add a new remote from my local repository to the newly forked Octopress?</p>
