  <p>Why can't I create a superuser login? Why do I have to use a third party?</p>
</blockquote>

<p>You <em>can</em> create a Super User login. What you'll get is an OpenID created by Stack Exchange, the owners of Super User. So this isn't really a third party option.</p>

<p>You can also choose third party OpenID providers such as Google, Facebook or Yahoo!</p>

  <p>What are your quality standards? </p>

<p>Explaining everything that applies here would take a while, but to summarize in a few bullet points:</p>

<ul>
<li>Be clear. If you're asking a question, imagine that not everyone sits in front of your computer to solve the problem for you. See <a href="http://superuser.com/questions/how-to-ask">How to Ask</a>.</li>
<li>Make it relevant. Answer a question only if you can solve the problem. See <a href="http://superuser.com/questions/how-to-answer">How to Answer</a>.</li>
<li>Use proper formatting and capitalization. Use a spell checker.</li>
<li>Always cite your sources, and quote passages you didn't write yourself.</li>
</ul>

<p>Because <a href="http://superuser.com/privileges/comment">you need 50 reputation</a> to be able to do so.</p>
