Models.com talent pages (models, photographers, stylists etc) are made on an invite-only basis and have nothing to do with Pro Membership features. If you are an artist/model with a page on Models.com, your page will continue to exist and you can manage the page regardless of whether or not you pay for a Pro Membership.

Similarly, upgrading your Models.com membership does not create you a page in the Models.com database as an artist or model. These pages are made on an invitation-only basis based on career accomplishments, longevity and industry influence.
