I'm working on the usability of my site and changed the order of the Primary Links menu items (which on NC Communities are in the upper right corner: Logout, Home, About, Help).
In the Chameleon theme, those links appear on the left side, above the navigation bar. I wanted to put an "Add Information" link there for people who want log in and cut to the chase.
Under Administer > Site Building > Menus, you can change pretty much everything about the menus: the order in which they appear (using the weight feature, -10 [top/left] to 10 [bottom/right]), the menu names, and the tool tip popup text. (Also in the same place, you can change the Menu Items in the navigation list, and change the placement (left side vs. right side) and order of navigation menu items.)
I added "Add Information" as a new menu in the Primary Links section and put in the full URL http://scrapexchange.nccommunities.org/node/add. Worked great.
I did a bunch of other things then logged out to make a comment on this site, then logged back in and noticed that "Add Information" showed up on my login page. Oops, don't want that. Users can't click to Add Information on my site before they're logged in, they get an "Access Denied" page.
After a fair amount of bouncing around trying to figure out what controls that, discovered that putting in just the relative URL -- node/add -- as the Path makes it not show up until the user is logged in.
Don't know if that comment is useful or not but the solution was not obvious so wanted to mention it.
