I am not altogether sure how this works but if it seems that a thread is being rated poorly because someone does not agree with the inital poster this would be a form of bullying. I would prefer that we only had an option for rating a post as excellent with a five star rating to avoid this problem. It is a pity that something that could be used to draw attention to a thread that is of great importance to many people could be childishly misused. If this is not possible then anyone noticing a poor thread rating could just pop into the thread and add an excellent to balance things out. As someone in a different thread stated we are all parents and people dealing with a very difficult and trying medical condition and should not have the extra burden of people passing judgment or publicly ridiculing or even just being plain mean.
