Nobuddy was really named Resident, I reckon; that was jes a placeholder. Any script that calls somebuddy Resident nowadays is obsolete (or usin' obsolete commands).
I dunno if I buy this "even oldtimers can change their last names!" 'cause how th'heck would that work? My username is samm.florian. Are they gonna let me change my username? I reckon not. So is my new name gonna be Samm.Florian LastName?
sammflorian from 2008 and on I've been around and lots of people were wanting to change their names. I think today's SL'ers are pretty much as they always were, fickle.
