Facebook Is Testing Ability To Designate A Group Member As An Expert and Other Comment Voting Features

The ability to designate a group member as an “Expert will help group admins highlight members with specific skills, knowledge, or a track record of being able to assist other members on a given topic.

Facebook is also rolling out its comment voting feature to more groups. This new version includes the ability to tag what you liked about a specific comment e.g helpful, kind, educational. Facebook badges can then be awarded to group members based on upvotes + tags.
