A few people have asked me about embedding other pages into their own site (like if you had a separate scheduling service). It's actually simple. Create a new page , click the Source button to insert code like you do for Google Analytics or some of the other tutorials, and add the following (substitute Google with the site you need wrapped). You can adjust the height so you see the entire page.

<p><iframe scrolling="auto" src="http://www.google.com" style="border-style: hidden; width: 100%; height: 600px;"></iframe></p>

Then click source again and save.
