The Metadot Wiki includes these content placement gizmos:
Blurb Editor
File Manager
News Manager
Discussion Forum
RSS Fetcher
Input Form
Calendar
MetaDog
Use the Navigation Panel on the right to go to a description of each gizmo. The navigation panel is part of this wiki design. It will appear on every page. The benefit is that you will always see the subpages of the current page. If you prefer to have more compelling content on the top right of the page, you can tweak this default design to move the Navigation Panel to the bottom of the right section.
