Publicly Viewable Group

If you say yes, most sections of your group will be viewable by anyone who visits your group - including people who do not have an account on this site.

Everyone will be able to see the group member listing, and see all discussions in the forums. However, people will still have to become a member of the group before they can post to the forums.

Regardless of this setting, your group file section and all files inside it will remain private.
