Ratings?

[Daemano]

SPAM and bad posts are common problems for forums. Traditionally, users send e-mail to the moderator to report spam. However, with Nabble, you manage spam by rating it as spam. This is equivalent to a 0 star rating. You do this by clicking on the to the left of the stars. If other users also rate down this post, its average rating will fall below the 2-star minimum and it will disappear from the default view.

Such bad rating will gradually carry over to the author's other posts, causing his future posts to be automatically filtered out from the view. This way the forum is self-moderated by all participants.
