title: how to make pull requests *without* a github account?
body: <p>One of the goals of git is to be decentralized. If Github is to be the ... hub of git, then maybe it could take into account that there are <em>other</em> hubs out there, and allow pull requests to happen on git URLs that are <em>not</em> hosted on github.</p>
  
  <p>The <a href="http://help.github.com/send-pull-requests/" rel="noreferrer">documentation</a> is fairly clear about this: pull requests require that you have a Github account and that you fork a repository <em>on github</em>. Is this a real current technical limitation or is there a way to workaround that on Github?</p>
  
  <p>If not, is it eventually planned to allow Github's "pull requests" tool to actually allow to pull from repositories outside of the Github silo?</p>
