Adding RSS feed that is ONLY for GROUP MEMBERS?

Question

I would like to make an rss feed that is only available for group members. Yahoo claims

"Every Yahoo! group has its own RSS feed. To read it you must either be subscribed to the group, or that group must be configured to have publicly-readable messages."

I see how to make messages public, but how do I make messages private and still available for RSS to group members?

Answer 1

you cant

Answer 2

I guess there is no way to do that.
