About Karma
Member Karma is a way of ranking each member based on their contributions to Newschoolers.
Members accumulate Karma points for uploading, posting and rating content. Many types of contributions are considered, and some are weighted more heavily than others. Members may also directly rate other members through the Karma XChange. You may add or remove Karma points for each member through their profile, and directly in the Forums beneath each poster's name. The Karma XChange value takes effect immediately.
Every night, points for new contributions like posts and uploads are added to each member's Karma rating. If a member's post or upload has been removed by a moderator, the member will also lose the associated Karma points.
Karma Tips
Don't piss members off. Being rude will just earn you a low Karma XChange rating which will drag down your overall score.
Post content. You get points for content you post and feedback you gather such as comments and ratings. Keep in mind that negative feedback or having your content removed results in Karma point loss.
