title: Installing surround.vim plugin into Vim's plugins folder seems to have no effect?
body: <p>I've downloaded the surround plugin (surround.vim) for <a href="http://en.wikipedia.org/wiki/Vim_%28text_editor%29" rel="nofollow">Vim</a> and installed it into the plugins folder. I know plugins work there as i've successfully installed the NERDTree and TList plugins.</p>
  
  <p>Once surround is installed, i start Vim and enter insert mode <kbd>i</kbd> and type:</p>
  
  <blockquote>
    <p>"Hello World!"</p>
  </blockquote>
  
  <p>I then go to normal mode <kbd>Esc</kbd> and move the cursor into the text and press <kbd>c</kbd><kbd>s</kbd><kbd>"</kbd><kbd>'</kbd> and nothing happens!</p>
  
  <p>I've also tried deleting the surrounds using <kbd>d</kbd><kbd>s</kbd> and still nothing happens.</p>
  
  <p>Have you any idea why this plugin is not working? Do i have to initialise it in the <code>_gvimrc</code> file? Could another plugin conflict with this one?</p>
  
  <p>Any advice is welcome.</p>
