Took me to podcast link. Maybe broken? Think this forum is excellent idea, would like to see on my home page like some of the other forums.
Which RSS feed link are you using? The URL referenced on the Rick Steves Tours Forum, when you click on "Get the Rick Steves Tours feed" is https://community.ricksteves.com/travel-forum/tours.atom, which appears to be properly loading the feed for this forum.
Thanks Nikky. Was able to add it from my computer (just didn't work from Ipad, from same page - go figure).
