Is there any way to make a menu link *not* a link? I have a hierarchy of links in my menu, but one of the higher level entries needs to simply be a category, and not link to anything.  It is "Related Sites" and has a bunch of related links under it, but should not itself link to anything.  

Drupal doesn't let me save it without a URL, and vomits a bunch of errors if I try using '#'. 

How can I achieve this with a minimum of hassle?
You can try the Special menu items module.

One of its features is:


  User can create a new menu item and place either &lt;nolink&gt; or &lt;separator&gt; to the Path field
