Hi there! Usually, for historical reasons, we prefer to maintain information, but we want to respect your current identity and do understand that names and psuedonyms are a personalized representation of who you are. As your wording identifies this as a branding change (a pseudonym rather than a name change), would you be open to a compromise in this situation of including your name along with your new pseudonym?
