Your role (user category)
Your role is used for several purposes.
It will appear on your personal Publishers Marketplace Web page
(should you create one). And if you do create a Marketplace page,
your role will factor into search results to help visitors home in
on the information they're looking for. Your role is also used to
customize menus and pages throughout the site to best suit your needs.
If you select blogger as your role,
you will be able to use a special page template for your Marketplace
Web page, allowing you to post dated articles as you might do
on a genuine weblog.
Once you've registered, you'll be able to add a second role (category)
through your Publishers Marketplace Account page.
