We improved the wiki usability in our May release.  Now we have an updated tutorial video that matches the new layout:

• We moved the page menu sidebar to the left side of the page, where it cannot be overwritten by stubborn content panels.
• We added tabs above the page Edit, View, Page History and Comments.
• We added small Print and Delete icons on the top right side of the page.
• We added a popup that will remind you to save your edits if you try to leave the page while editing.
