title: Just starting with TortoiseGit, why does it need my email for a local repository?
body: <p>I just installed Git + TortoiseGit, created a new local repository on my PC, added a file, and now I'm trying to commit it (I guess that's Commit -> "master").</p>
  
  <p>However it says: "User name and email must be set before commit. Do you want to set these now?"</p>
  
  <p>Ehh, this is supposed to be a local repository. What does any email address have to do with this?</p>
  
  <p>Or am I misunderstanding the way Git works? Note that I'm not using GitHub or BitBucket or whatever. Just a local repository.</p>
