Currently we have RSS feeds for some slowtrav things (blogs, classifieds, trip reports, reviews) and some slowtalk things (recent 20 posts, weekly top 20 topics).
It turns out I had the RSS feeds setup already. You can find them in two places:
SlowTrav: http://www.slowtrav.com/rss/ - Subscribe to the message board or to latest vacation rental reviews, trip reports and classifieds.
SlowTalk: On the main message board page ( http://slowtalk.com/groupee/forums ), click on TOOLS and select RSS Feeds. There you see the ones setup for this board (recent 20 posts, weekly popular topics, weekly top 20 topics). These feeds are just for the Travel forums; other forums are not included.
You can view these feeds on our Top 20 Topics page - linked in the header of the message board.
