Going about under an assumed name, eh? (That’s the price of fame, I suppose.) The rules for changing your Popula username are: you can only change your username once every 30 days. Also, your comments stay with you, even if you change your name. And lastly, you should know that all your usernames are listed together in our records, so for Popula’s administration purposes, you’ll still be the same lovable person as ever.
