RSS Feeds for this forum that contains responses?

When I try to get an RSS feed for this forum (such as the latest: it only has the first posts rather than threads of posts and responses. A topic does seem to re-appear in the RSS feed if someone responds - but to see it I have to follow the link to the web site and then figure out what the new thing is.

Is there a way get such an RSS feed?

For the forums, there are two RSS feeds that I use, for posts it is this:

You already have the one for latest, which covers new topics, I believe.
