In development/general or other part, people ask question about many things. When you go the site and you do not understand that asker getting correct answer or not at a glance. In stack over flow They use different color for getting correct answer so people understand easily. I am just telling about that thing. Hope you will understand.
I thinks it's a good suggestion, may be nop team can look into this. But forums are not only limited to questions so may be it should be limited only to forum where questions are asked.
