Hello Miss Snark,
When do you tell your agent that you want to write under a pseudonym? When you query do you sign off as :so and so aka. so and such? Or not even tell them at all what your real name is and when it comes time to be paid: "Oh by the way could you make the check available to..."?
Um, you better sign your real name to my offer for representation or we're gonna have a talk about the fundamentals of fraud. This is not a talk you will enjoy.
Tell me who you are. If you write under a different name, you can put:
(writing as S.K. Inkslinger)
so I can see what you're doing. If you don't ever intend to tell me your real name, we have big problem cause I have to write you checks that you can cash AND fill out little forms for the IRS that require me to affirm this form is correct or face prison time. Now, Miss Snark is as fond of caged heat movies as the next gal, but she doesn't want to star in them.
So, tell me who you are, let me know you're writing under a pen name, and let me get busy making you rich and anonymously famous.
