Sorry, jackal - but that doesn't change my viewpoint. The person themselves may no longer personally identify with their handle - but everyone else on FlyerTalk probably does.
Personally, I don't like the idea of changing one's handle for that reason.
Spelling and/or punctuation errors, or to remove your full name if that's what you signed up with, fine - but to adjust a handle just because it's not representative of you anymore, not IMHO...
