RSS feeds can be used in both slides/templates and the live ticker.
In the section Create templates and slides you can find more information on how to use RSS feeds in the text fields of slides and templates.
RSS feeds can also be used in the live ticker. The section Function Plugins/Live Ticker Plugin provides information on how RSS feeds can be used in conjunction with the live ticker. Please note that a valid URL of an RSS feed needs to be entered into the text fields.
