Panzer almost didn't stop and read Ms. Lewandowski's post. Although the post is titled "A Suitable Pseudonym" it's actually about setting up your Author Central Page using a pen name. There is quite a bit of information about choosing a pen name before the post addresses the Author Central Page.
After the section on picking a pen name, the post makes the process of the Author Central Page setup easy. It has very detailed instructions and is loaded with screen shots. In fact, this is such a long post you'll need a very large cup of tea while you're reading it.
