Ill just answer the initial question  you are trusted to use your discretion to decide whether a particular edit has consensus or not but should exercise extreme caution when it is your own edits are called into question You are welcome to make a change to a template without discussion if you believe that it will be uncontroversial But you should then selfrevert if that change is opposed and not make the edit again until it is clear that consensus supports it I will now pop along to the template talk page to see if I can offer any suggestions Regards  Martin
