Why don't RSS Feeds work with my RSS reader?

Why don't RSS Feeds work with my RSS reader?

The offers, requests and exchanges in a Community Weaver 2.0 site are considered private. Members need to login to their Timebank to see them. Therefore the RSS feeds are behind the login and you have to be logged into the site to see them.  Google Reader and many others RSS readers do not support private RSS feeds and therefore have no access to the Community Weaver RSS feeds.
