remove something from navbar

[maryx]

I have a tab I want to remove from the navbar, and I can't remember how I put it in! I used firebug and found this
<li><a class="navtab" href="http://www.myforum.com/forum.php#thistab">Tab I Want To Remove</a></li>

The tab I want to remove is next to the Home tab, but I couldn't find it in any templates by doing a template search.

I looked at the page source with the templates turned on, and there is no template associated with this line.

I did not put it in with the tab mod I have installed, it doesn't show up there.

So, where exactly do I go to remove this tab?

Thanks very much!!
