I don’t think esmi understand the problem. mattzellmer is asking about how to remove the <p> tags around the html comments (not the blog user comments). I sometimes put some html comments saying what the <div> block is like
<!-- start of main content -->
<div id='maincontent'>
some other tags or content
</div>
<!-- end of main content -->
After I save this in the editor within wp-admin, WP render my content like this
<p><!-- start of main content --></p>
<div id='maincontent'>
some other tags or content
</div>
<p><!-- end of main content --></p>
This has caused a problem for the layout
