There’ve been questions about RSS feed(s). On the sidebar on the right, down at the bottom, there’s a section headed “Meta.” There they are. I feel really…unobservant, if not stupid, for not noticing that before. My web guru, when I asked her to add RSS, pointed out they already existed. Hope this helps!
On Firefox, when a page is RSS-able (if that makes sense) there is (or can be) an icon on the toolbar which you click and it asks you whether you want the post feed or the comments feed, and you basically take it from there. Couldn’t be easier.
