How does voting on ideas affect my status points?

As with other things you do in the community -- creating content, responding to discussions, and so on -- your actions on ideas contribute points to your overall status points in the community. (If you aren't familiar with your status points, you can view them on your profile page.)

Depending on how your community is configured by your administrator, you may earn status points for the following (typically, you earn more points for creating ideas and less for commenting or voting on them):
