What does the module do?

same question ?
havent find nothing on google ??

Bump.

I say it with love, but that module description is kinda lame. Even a link would be enlightening.

Karma is a comment rating and community participation system to try to keep the comments as high-quality as possible. All users can rate all comments, except their own, between 1 and 4. When your comments are rated by others, those ratings are combined into a weighted average -- newer comments count more than older ones -- called your "Karma". This, roughly, represents the rating you could expect your next comment to receive based on your past comments. Users who have a karma greater than a certain minimum and who have posted a sufficient number of comments are considered "trusted" users, and have the added capability to rate comments below the normal minimum rating (in other words, their rating scale is 0-4, rather than 1-4.) If enough of a user's comments are rated below 1, that user becomes "untrusted", which means that respected members of the community have repeatedly indicated that the user's input is offensive, content-free, or merely intended to annoy others. Said comments no longer appear for anonymous and regular users. Only trusted users can view them.

Many users believe that the rating system is intented to be an opportunity to express agreement or disagreement with a post, or with the poster themself. This is not accurate; ratings are intended to help elevate those posters that consistently make clear, good arguments and points, regardless of content, and to prevent trolls from invading the message board. Downrating commenters on the basis of agreement or disagreement with their arguments leads to a monolithic forum, free of new ideas and input.

So, please don't downrate comments just because you disagree with them!
[edit]

Uhmmm... How 'bout updating the module description on the project node?
