i'm being given the option to use either my legal first name, or my 'preferred' name in my school email address. suppose my name was robert doe, but the last time anyone called me robert was in kindergarten. everyone and their mom now calls me 'bob doe'. should i make my email address robert.doe@ ? or bob.doe@?
(feel free to replace robert/bob with jonathan / jon, christopher / chris, or any other short form of a longer name).
i guess the real question is - would it be too informal to have my shortened nickname go on my business cards / email address, even if that's what everyone calls me?
