Guidebox

Due to the fact that MediaWiki can be a bit confusing at first, I figured I would assist with a little guidebook aka "Guidebox". This box resides at the bottoms of each Navigation Portal (the five pages in the Left Sidebar under "Navigation") and will eventually contain links to different pages or tutorials that will help a person get more acquainted with the site. Of course, these pages and tutorials still need to be written, but the fact that the Guidebox exists will help to remind me of that necessity.

Question is, what sort of information should the Guidebox share? I see it as a mini Help page with some easy links to things particular to this site. In other words, it might have some commonly used links that didn't make it to the Left Sidebar. So what would they be?
