I’m employed at a computer security company and have a colleague whose name is M. Alware. His e-mail address is firstname.lastname@example.org.
My ex-boss’s name is R. Stone. His e-mail was email@example.com.
My name is James Pan. Every other permutation of my name was taken (e.g., jpan, jamesp), so I’m stuck with firstname.lastname@example.org.
