We've just added a feature to rate posts as "Helpful" or "Not Helpful." If you are registered and logged in, there are two new links to the left of a post, under the posters name. When you click on one you rate the post, and the forum members overall rating score is adjusted.
We added this feature to help make it easier for new users to identify information that's been useful for other users, and to be able to see who the good sources of information are on our forums.
While you are reading a post, please take an extra couple seconds to think about the post and rate its helpfulness.
