I believe all of the links in the top navigation bar have a copy in one of the three nodelets among Sections, Find Nodes, and Leftovers. As a special case, Leftovers links to your homenode and logout, Find Nodes links to Super Search. (Leftovers, however, has lots of useless links to pages outside perlmonks, which I'm hiding by css right now. Maybe they should be factored out to a separate nodelet.)
