This plugin lets you add a fully functional BuddyPress activity stream to any page. Designed to match the native BuddyPress activity feed, you can now post and see activity from wherever you like.
Simply add the shortcode [activity_feed_anywhere] to any page on your site.
If you would rather not display the feed, but only the ‘post box’, simply use [activity_feed_anywhere feed=false ]. Activity entered here will show up in activity feeds elsewhere in the site.
If you would rather not display the post box, but only the feed itself, simply use [activity_feed_anywhere postbox=false ].
