This IS a pseudonym actually. So probably Beck Nicholas...
Why... well Beck is what I'm called usually anyway so it's kinda my real name. And I'm scientifically published under my last name so that's like a different side to me. Nicholas is someone i adore's middle name.
If I had to choose a different name altogether I would still use Beck of some sort because I can't imagine answering to anything else. As for last names... It has to matter. Cos if i get to choose I want it to mean something. And sound okay. And not spell out something offensive.
What about you? What matters to you when choosing a pseudonym? Does the name have to link to your family/life? Can you answer to a different first name (am imagining all those signings in my future)?
