Todo lists on individual member profiles are one of the most effective engagement tools that can be used on social networks. The easy to configure BuddyPress User Todo List plugin allows you to have private to do lists for each user, all users to share a to-do list or to even have a master list with individual completion of items.
An effective engagement tool for your users, the BuddyPress Member Reviews plugin is ideal for sites that want to allow their site members to post reviews to the other BuddyPress members on their site. Only the site members can add these reviews. Moreover, the member can not review himself which makes it the perfect choice for job portals and LMS.
