Is there a way to save/bookmark HN threads under my HN profile? I see "saved stories" under http://news.ycombinator.com/saved http://news.ycombinator.com/saved

Is there a way to save/bookmark HN threads under my HN profile? I see "saved stories" under http://news.ycombinator.com/saved http://news.ycombinator.com/saved, but don't see a way to save anything there. The only other option is to comment on something and then have it available under "threads", but that sucks. Sorry, I'm a newbie around here.
