Well this suggestion could go hand in hand with the like button, but it's slightly different. While you can like a post, that doesn't mean it's 100% helpful. A lot of blogs have comment systems where users can rate posts as helpful or not and when they reach a threshold they are automatically hidden. It would be great to have a feature like this where we can set the ability for users to mark posts as helpful or not. Making it customizable for each individual forum and limiting it to particular usergroups would be great as well. If a post has been marked as negative, it would be great to ghost that post with a little warning for users stating "This post has been marked as unhelpful and may not be worth your time." Then they can open the post if they so choose. What do you guys think? EDIT: Sorry, I thought Suggestion was a prefix that is automatically applied.
