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!

Places a 468x80 pixel advert inside the header of Automattic's wonderful P2 Theme.

P2 Likes brings Facebook-like functionality to your P2 site. Your users can now show interest in threads by clicking the like button.

P2 Likes

Works just fine on latest WordPress, even under Mercury child theme, although I'll have to do some styling for the avatars of those who liked a post or comment (they get slightly cropped on the right side).

Give positive feedback on threads you care about on P2
