Administer>>site building >> modules >> bookmarks

What I see :
Bookmarks List Add Group
I click on Add group.
I see: MenuName Title Description

I key: testmenu, testtitle, testdescription and click Save.

I see: testtitle, list items, add item, edit menu & the text tells me there are no bookmarks yet.

I click on: Add item hyperlink

I see: Menu link title, Description, Enabled checkbox-set, expanded checkbox-not set, public checkbox-not set, parent item , weight 0

I key: testlinktitle, testdescription and take the defaults on everything else and click save

I see: testtitle page again only this time I have an item called testlinktitle

If I click on testlinktitle (which is a hyperlink) I get the page to add another item.
If I click on operations-edit hyperlink, I get page not found
If I click on operations-delete hyperlink, i get page not found.

I am unclear where I would put the 'external url. I am missing something.
