What is voting up?
Voting up is how the community indicates which comments are most useful and appropriate.
When should I vote up?
Whenever you encounter a comment that you feel is especially useful, vote it up!
How do I vote up?
Click the large up arrow under a comment.
You can undo your vote by clicking the same button you used to vote, so click the up arrow to undo an upvote or the down arrow to undo a downvote. To change a vote from up to down, click the down arrow, and vice versa. Votes can only be changed for a short period of time, so be careful with those clicks!
What happens when I vote up?
When you vote up, you are moving that content "up" so it will be seen by more people.
