What is voting up?
Voting up is how the community indicates which questions and answers are most useful and appropriate.
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?
When you vote up, you are moving that content "up" so it will be seen by more people.

- Upvotes on an answer give the answerer +10 reputation.
- Upvotes on a comment help ensure the comment remains visible when there are many comments on a post, but do not give the author any reputation.
- You can vote 30 times per UTC day, plus 10 more times on questions only.
