The group Forum is a place where members can exchange public messages on various topics, allowing many people to join in an ongoing discussion.

Any member can post a new topic or post messages to a topic already on the site.

This is a great way to have an online discussion about upcoming plans, like scheduling meetings or deciding what to do at an upcoming event.

Some members can be set up as Forum Moderators.  They can edit or remove posts they find objectionable.
