Can I Sign Up With a Pen Name?

Can I Sign Up With a Pen Name?

Hi,

I asked this question directly to Support but since it was not an emergency question they haven't gotten back to me, and it's been about a week.

Far as the Terms of Service are concerned, can I sign up with a pen name or do I HAVE to use my real name? I want to keep my blogging and publishing separate from my real name for a small form of privacy, and also for marketing reasons (Sometimes people just don't remember really long first names and surnames, and keeping it short makes your job much easier), so I'd like my personal and then business email separate.

Long question short, can I use a pen name? It'd be consistent with it, and I think most would know it's an alias.
