+=== RSS 2.0 Feeds ===
+
+By adding the `format` parameter, an RSS feed resource can be produced:
+
+{{{
+http://example.com/moin/FrontPage?action=EventAggregatorSummary&category=CategoryEvents&doit=1&
+format=RSS
+}}}
+
+This resource produces a description of all events within the stated criteria. Updated events should be detected by feed readers and each subscriber notified of such updates, with the comment made when the affected event was edited being provided as the event description in the feed.
+
+A technical note: feed readers will typically detect updated events by consulting the content of each event description's `guid` element, notifying the user of changes if the content of that element has itself changed.
