Setting up a group to publish its content as an RSS feed

(Short answer now; more complete answer later)

Create a view that shows the last XX (as desired) number of items for a given group. Set it up as an RSS display. Use the group ID as an argument.

This will create the RSS view (and URL path) for the feed. However, it will not show the RSS icon, or create a link to the feed anywhere on the group home page.
