So I'm continuing to learn this second hand site's features, as I skin them. One thing I noticed is that this site doesn't seem to use the "menu" options or the "categories" at all. Instead the menu is a custom, and kinda badly done, javascript thing that is not in the customer's power to control. IMHO, the whole point of a CMS is to allow the customer to manage their content, so I'd like the customer to be able to manage their own menus.
As such, I assume that there's a way, using this "menu" thingy in the content section. I tried creating a new menu, but can't figure out how to add links to it.
