If you need to access the Topic RSS for any reason, there is a "link" button at the top of the platforms screen. Once you click on the "link" button, there will be a drop down and give you a few different options. To copy the RSS link all you need to do is press the "Copy RSS Feed URL" button and the RSS link will be copied to your device's clipboard.
This is useful whenever you are planning on adding a Topic's RSS feed to your website!
NOTE: The articles presented within the RSS feed will match the sorting and filtering settings presented within the topic at the time you copy the RSS feed URL. If you need to edit a topic, click here!
