ah, good catch. I don't know if I'd call it a bug though ;P Although it does make me wonder how the menu system works in that regard... if extra links will be manual (template edits) or if it can be achieved another way.
I actually think the copyright would be better placed after breadcrumb, and that terms of service/privacy policy/whatever should go next to Contact Us.
Curious if the links that are shown in the drop-down are hard-coded or if the links that get presented in the left sidebar are somehow flagged as being also to be shown in the drop-down? (Kind of like 'add a section/item/entry to the left sidebar and flag it to also be in the drop-down'.)
