I really don't see the point in this unless it is involving a problem with the site or another member. The solution to that problem is PM'ing a staff member or admin.
I too don't really see a point in this. If you have something to say, Say it. This is a forum not person to person. If you can't say something to another member here than thats a pretty big problem. And if you are trying to say something to staff without them knowing its you that wouldn't work as we would still have your ip, And could match it to your account. So honestly this is pointless. If you have something to say, Say it.
