Welcome to Wikipedia. We welcome and appreciate your contributions, including your edits to M&M's, but we cannot accept original research. Original research also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You need one reliable source discussing M&Ms and vegetarianism. Otherwise, we could just as easily add info re M&Ms and veganism, lactose intolerance, chocolate allergies, peanut allergies, diabetes, the paleolithic diet...
Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, talk pages are meant to be a record of a discussion; deleting or editing legitimate comments, as you did at Talk:Dead Parrot sketch, is considered bad practice, even if you meant well. Even making spelling and grammatical corrections in others' comments is generally frowned upon, as it tends to irritate the users whose comments you are correcting. Take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. TJRC (talk) 20:58, 20 August 2014 (UTC)
