I am using Drupal 7 and working on a rating site using Fivestar and Userpoints.
What I want is for a certain amount of points to be deducted from a user when he makes a post, and also points deducted from a user when he votes on a node.
The rating and points deduction works well, but the issue is negative points. I don't want any user's points to go below zero. I need to prevent users from having negative user points on the site.
