This site has full RSS (Really Simple Syndication) news-feeds for both new topics and replies to existing topics for those who wish to keep up-to-date with what's going on without having to browse the site. Ideal for those who are using mobile devices. The news feeds give you a snapshot of the post and a link inviting you to read more and respond yourself.
Could well be some setting I have, but the feeds don't seem to be updated. I'm using the RSS tool that displays on the desktop of Windows 7 (A gadget apparently) and this morning it's still only showing the stuff from yesterday.
