1. Create a new wiki page, then choose to edit that page.
  2. In the edit view click on the button that looks like a TV set (add a widget).
  3. Choose "other HTML" and paste the following code in the window: <object data=http://www.embeddedpage.com width="600" height="400"> <embed src=http://www.embeddedpage.com width="600" height="400"> </embed></object>
  4. Replace both instances of http://www.embeddedpage.com with the full address of the page you want to embed.
  5. If you want to adjust the size of that embedded page, adjust both instances of the number you'd like to change. For this wiki, width="800" height="600" works well.
