title: How can I remove a tag from npm?
body: <p>I've published a grunt plugin to npm that's been tracking the grunt 0.4 RCs by using the <code>master</code> tag. I've been publishing with:</p>
  
  <pre><code>npm publish --tag master
  </code></pre>
  
  <p>Now that grunt 0.4 final has been released, I've re-published my plugin as <code>latest</code> via:</p>
  
  <pre><code>npm publish
  </code></pre>
  
  <p>How can I now remove the <code>master</code> tag from the npm repository? It is still listed in <code>dist-tags</code> when I <code>npm view [my-plugin]</code>.</p>
  
  <p>Thanks in advance.</p>
