If this feature has or ready been suggested, I'm sorry. I could not locate this in my profile. Similar to how SMF does it. Login with your username (what you register with) however, everywhere your name is displayed, it displays your display name. An example is, I register at community's with the username Acans (because its never taken), however if I have the option, I change my display name to ѕησω. Why I do this? Personal preference.
