Difference between “Visiting” and “Joining” a Group.
Members can visit almost all groups. However; they must join the groups in order to interact with the group.
Joining a group give you the ability to post topics, discussions, status updates, etc. with the ability to reply to other members’ posts.
Another way to join groups is by visiting them first (see below):
After Joining a Group, you will find new options to post topics and reply to other members.
If you scroll down to the bottom of the topics, you will see this option for creating a new topic.
When reading topics from other members, you will see the option to “Reply.”
