I hesitated posting but I have been unable to find the answer.

1) How Can I add my own parent menu listing and then add child, sub-categories? Is this done with the categories_ul_generator? If so is there anywhere in this thread that describes how?

2) In my menu the text must read CONTACT_US. When editing to Contact Us (No underscore) in tpl_drop_menu.php something breaks and I lose the site.

I do appreciate any help!
