Lets logged-in members repost a post, page or custom post type to the BuddyPress activity stream, the way a post is shared on a social network but kept within the site. Logged-out visitors are asked to log in first.
The Repost link appears for any post type BuddyPress tracks as activity. Themes can show it with the Repost link block, for example in a post’s footer inside a Query Loop, or by calling lh_buddypress_repost().
