By enabling voting in your Board’s settings, you give your users the chance to show their approval of each Boomerang.

Voting Basics #
Your users simply click either the up or down arrow to register their vote. Users, including Boomerang Managers, can only vote once per Boomerang, however they can change their vote. This prevents them from voting a Boomerang up (or down if downvoting is enabled) more than once, and thereby vote-spamming.
Downvoting #
There are two ways you can choose to offer voting. If you enable downvoting, users will be able to vote up a Boomerang, remove their vote, or even vote down a Boomerang. With downvoting disabled, users will only be able to vote up, or not. The choice is yours, and will depend on your particular use case. In simple terms, by allowing downvoting, you give users the power to register their disapproval, as well as keeping a neutral position.
Bulk Votes #
As explained above, Boomerang Managers can usually only vote once per Boomerang. By enabling Bulk Votes, this restriction is removed. This can be extremely useful if you have imported Boomerangs from elsewhere and need to adjust the vote score. There may be other times where you feel you need to inflate or deflate the vote score manually. We recommend disabling Bulk Votes at the conclusion of any changes, to prevent any accidental clicks on the vote button.
