8. Contact
This page uses "Default Template" you can find inside the "Page Attributes".
8.1 Left Content Part
The contact form itself is built using Jetpack Contact Form but you are free to use any other working contact form.
8.2 Right Sidebar
To fill it with the content navigate to Appearance > Widgets > Right Sidebar and add your content inside. Special Jetpack feature "Jetpack Widget Visibility" allows you to have different sidebar content on different pages using the same sidebar. That means you are able to have one content inside the right sidebar on the about page and other content inside the right sidebar on the for example "News Page". This gives you a great amount of creative freedom! Read more about it here:http://jetpack.me/support/widget-visibility/
