There has been an addendum to the forum rules concerning the use of the Karma Feature. I've included the new rule in this post and request that anyone who wants to review the site rules in their entirety to please follow the rules link. If there are any questions, please feel free to ask and I'll be happy to clarify.

Karma Feature: Karma points are not a method of punishment or reprimand therefore, negative Karma will not be tolerated on the forum. As for awarding Karma points, this should be done in a way to support members or as a reward for hard work. When you give karma, it should be done with frugality in order to maintain the value of its reception. As a rule of thumb, one or two points for any occasion should be sufficient and thus shouldn’t be exceeded. Inversely, using Karma as a bribe or giving it away frivolously is not an acceptable use of the Karma feature. And demands for Karma are likewise, forbidden. Acceptable uses for positive karma include: rewards for challenges, rewards for a particularly enjoyable comments and posts, rewards for assistance (i.e. fanfiction search, etc).
