 is a preset allow/deny scheme. It allows all hypertext tags (basic text formatting, images, and horizontal rules) but doesn&#39;t allow tables, forms, lists, or other complicated tags. This will make it match the capabilities of <i>AOL Instant Messenger</i>&#39;s HTML rendering widgets.</p>

<p>It will allow the following tags:</p>

<pre><code>  &lt;html&gt;, &lt;head&gt;, &lt;title&gt;, &lt;body&gt;, &lt;a&gt;, &lt;p&gt;, &lt;br&gt;, &lt;hr&gt;,
  &lt;img&gt;, &lt;font&gt;, &lt;center&gt;, &lt;sup&gt;, &l
