In this very short essay, I explain why I choose to write my name in lowercase.
When I was 12 I joined a server where everyone’s name was their first initial and the first four letters of their last name. So my username was “msenn.”
After a while we migrated systems and the rule was relaxed, and many original members changed their names to be more phonetic—I added an e to the start of mine, to become “emsenn.”
Because my name originated as a username, I always write it in lowercase: a nod to my heritage.
(And yes, everyone calls me emsenn, even in real life.)
