title: RSS feeds for other stackexchange pages
body: <p>I use</p>
  
  <pre><code>http://stack2rss.stackexchange.com/stackoverflow/users/429540/favorites?body=true
  </code></pre>
  
  <p>to receive information about stackoverflow updates.</p>
  
  <p>I tried to do the same with </p>
  
  <pre><code>tex.stackexchange.com
  </code></pre>
  
  <p>and</p>
  
  <pre><code>askubuntu.com
  </code></pre>
  
  <p>by modifying the url in the obvious way (replacing stackoverflow) but it does not seem to work. Any idea if and, if yes, how I can receive rss updates for these pages?</p>
