KB wiki-4
From SWCP Support Wiki
The navigation bar on the left-hand side is editable, like any wiki page (well almost). The page name is MediaWiki:Sidebar.
The entries look a little different than a normal wiki page and are assumed to be a page reference. For example, if you want to change the "navigation" box to contain 2 links, one to your knowledge base and one to your products list, the page should look like:
* navigation ** Knowledge Base|Our Knowledge Base ** Products|The XYZ Product List
