Posting a Comment
What is that thing when you post a comment and there's the up and down arrow you can click on? What does that mean?
If you press the up arrow, you indicate that you like the comment; if you press the down arrow, it indicates that you don't like the comment.
And if five cumulative people push down the post is removed from view subject to later review by a moderator but I don't remember seeing anything come back from being downvoted
