Hacker News Documentation

Is there something like this?

I just noticed the "saved: 7" in my profile. And my guess was that this is a list of Comments I upvoted. I tried by upvoting a random Comment. And it seems to work. But how do I get rid of it again? Or in other words - how do I downvote? Or more generally: How do I find out how to do stuff?

So, you're basically asking for comments? (as in code comments, not snarky responses) ;)

Some things are tied to karma, having karma above a threshold value will allow you to make a bigger mark on the site.

Has any "saved" thing ever disappeared from YC?
