title: Cornerstone SVN Error - Cant commit files
body: <p>Do users under passwd in subversion have certain permissions?</p>
  
  <p>I can download all the files from my subversion repository using Cornerstone on mac.</p>
  
  <p>But, if I make a change to a file and try to commit the file back to the repository...</p>
  
  <p>Cornerstone gives me this:</p>
