Once installed, head over to Appearance – P2 Header Ad and paste your ad code into the box.
Features:
<ul>
<li>preview your ad in the admin interface (see screenshots)</li>
<li>option to hide the ad for logged-in users</li>
<li>option to hide the ad for logged-in WP eMember users</li>
<li>works with and without a header image</li>
<li>option to show the same ad after the post content</li>
</ul>
I’ve optimised the plugin for a 468×80 pixel ad. Other sizes will work but may require your own CSS tweaks to make them look right.

Works just fine! I'll use it for internal important notifications but definitely saved me some time for writing this feature myself :)

Nice!

Add support to the P2 theme for Jetpack Infinite Scroll. This will also automatically hide the default “Older posts” link in place of the infinite scroll button (for visitors that have JavaScript enabled).
