I am subscribed to a rss feed. Each post in the rss feed can be commented on and there are rss feeds of the comments (1 comment feed per post in the main feed). Is there anything I can do to make subscribing to these comment feeds a one click operation? I tried setting the item link in the main feed to the location of the comment feed but when I click on the title it opens the "do you want to open or save" dialog instead of letting me subscribe to the feed. Any ideas?
