How to Improve BuddyPress Pagination
Occasionally BuddyPress site owners inquire about how to change the default number of members or messages on BuddyPress pages. Check out the BuddyPress Better Pagination plugin. It adds pagination links at the bottom of all directories in BuddyPress – in groups, forums, members, friends, blogs, messages and allows you to set how many items show per page. Bottom pagination will be added to the BuddyPress core in 1.2.6. This plugin does that for you now and adds an extra menu item: BuddyPress >> Better Pagination. Here you can adjust items per page.
