I would love to see similar functionality as an out-of-the-box feature of Totara. Ideally it would be something customizable with different options like upvote/downvote, likes/dislikes, hearts, emoticons, etc.  Allowing users to "like" posts in some way is a great form of interactivity which should increase user engagement as well as the perceived usefulness of the LMS. If there's already a similar feature request, let me know. Otherwise I will make one. Thanks for all your help!
