eXceem have used FeedBurner to help distribute its RSS feeds (though if you are familiar with vbulletins RSS feeds, these can still be used)
The advantage of feedburner is that it allows easy integration with popular portal sites.
There are 4 feeds currently setup with feedburner, new posts, new threads, new news items & the podcast. If you want feeds for any other parts of eXceem feel free to ask
