# What are "Forum" spheres?

The Forum option can be enabled by a sphere administrator in the sphere settings.

The correct responses to messages can be qualified and highlighted, and the incorrect responses can be blurred.  

The forum feature lets you validate comments on a message. When a user posts a comment, it's noted as "Pending". The sphere administrator can then refuse or validate the comment.
