What is voting up?
Voting up is how the community indicates which questions and answers are most useful and appropriate. Both posts (questions and answers) and comments may be voted up.
When should I vote up?
Whenever you encounter a question, answer or comment that you feel is especially useful, vote it up!
You have a limited number of votes per day, so use them wisely.
How do I vote up?
Click the large up arrow to the left of a post, or the small up arrow to the left of 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 posts?
When you vote up, you are moving that content "up" so it will be seen by more people.
