Looking at one of your latest changes here in the Discussion Boards i just keep trying to understand why you have made this kind of distinction between the posts. I am talking about the green background that exists in posts of Moderators etc.
If you were going to create a system from which the initial poster would select as acceptable solution a post then ok, that would be acceptable to mark it to be easily able to find what you want (like many other sites do). But in this case i don't see the reason why the posts from some people have to be different from the others by default.
To make my self clear, it's nothing personal with none but it's just a thought i wanted to express.
