How do I enable only registered users to see yahoo group messages?

Question

Hello, I have started a Yahoo group, however, at present, anybody can view messages posted on the forum, i.e. those who have not signed up to join the yahoo group.

How do I disable this feature so that only members of the yahoo group can view messages?

I have checked other yahoo groups and their messages are not publicly viewable
