Anonymous contribution has long been the favored approach to wiki editing, but if you use a UserName, it should be your RealName.
Some users have chosen to adopt DramaticIdentity names as UserNames. This is:
If you are using DramaticIdentity to hide your RealName from WikiVandals, consider removing the UserName cookie completely. Violating WikiSocialNorms with DramaticIdentityAsUserName may lead others to assume you are a vandal. By editing without a UserName cookie, you are allowing other users to identify your actions as your own, and prevent WikiVandals from coopting your DramaticIdentity to cloud others' view of your actions.
