RSS (Also 'Rich Site Summary') is a family of site syndication files stored in XML. Since V7.5, opera has the ability to read RSS feeds (versions 0.9x/2.0 and 1.0) using an interface through its communications client, M2. RSS files will auto-install when clicked on.
Opera’s feedreader will strip any tags from the feed, and only display plaintext messages. Any links will be made clickable for easy use.
