[Private! WordPress Access Control Manager & BuddyPress] RSS Feed

I am using PWACM and BuddyPress to administer my chorus’s members-only website (members.49erschorus.org). I want my users to be able to use Atom or RSS to have posts delivered to them. But, the URI isn’t working. I suspect that has something to do with the password-protected access to the site.

Is it possible to set up an RSS and/or ATOM feed link for the site that allows them to authenticate with UserID and Password?
