I think it would be nice if for the star rating we at least get rid of the zero star rating. I personally want people to suggest how I could have done my cake so that I can learn on to do things differently. I know that I don't get my cakes smooth as I want, but because of all the advice on this site from all people I am working on making it better.
Sometimes when someone asks for help the person who has done that particular task may not be on to give the advice, but another person may have seen it somewhere else so they give the advice. I think that if you have not done it but know where you read it you should state that in your post. I try to do this alot. I am really good at finding things for other people and will say I saw this here or I will post the answer as a quote or I will point the person to the area where I read it. I always want to help people, and think good communication is key. I personally want advice from all kinds of people, even if they haven't tried it. Does not mean I will use it but I will still take the advice to heart....ok now that I have rambled on enough and meant in no way to hurt or offend anyone, I am just stating my opinion which is everyone is entitled to
