Using RSS feeds
From Carleton Moodle Docs
Activities and other areas that produce RSS feeds
Subscribing to RSS feeds
To subscribe to an RSS feed from Moodle, click on the activity and look in the Administration block for a link "RSS feeds for (this activity)" and copy the address from your browser bar to your RSS reader software.
Restricting access to RSS feeds
To ensure security and privacy, RSS feed URLs contain a special token that identifies the user they are for. This prevents users from accessing areas of Moodle they shouldn't have access to via RSS feeds.
Users have this token automatically created for them the first time they access an area of Moodle that produces an RSS feed. If a user feels that their RSS feed token has been compromised in some way they can request a new one by going to the User menu > Preferences > Security keys and clicking the Reset link next to the RSS key.
To provide a public RSS feed for use on another site, login to your Moodle site as a guest, then copy the RSS feed address. Make sure guests do not have to agree to a Site policy document.
