i've made a visible link to a page that has an overview of the different RSS feeds. previously i was relying on the browser to report RSS feeds. for some reason, browsers don't do that well. Firefox doesn't seem to do it at all anymore.
i've also improved the feed for comments on your problems, so you can see the path now.
New RSS page
Re: New RSS page
Great! Just when I was wondering where the RSS feeds had gone. The twin diagrams of the initial position and with numbered stones indicating the variation commented on are a great asset.
