Help:VBulletin:RSS and Podcasting
Can I use RSS to keep up with new posts?
If the administrator has enabled RSS syndication, this lets you view newly created threads in guest-viewable forums without visiting the board.
The feeds are currently provided in two formats, RSS and RSS v2.
Most modern browsers have facilities for reading RSS feeds and will automatically detect the availability of feeds on bulletin board pages. How do I listen to podcasts?
A podcast is a means of distributing audio files (such as .mp3s) over the internet. They can be played on a wide range of media players and computers. If the board administrator has enabled this function, then you may sometimes see links to podcasts within threads.
Podcasts contained within threads are only accessible using RSS feeds.
