EBSQ Self Representing Artists is an online community for artists who want to take control of their own art careers. They describe their site as a hub where you can house your full portfolio, link to all of your online venues, easily establish the provenance of your work with their Digital Certificate of Authenticity tools, and connect with a global art community of artists, artisans, book artists and photographers.

There is a membership fee for artists. I did email to enquire about how much their membership fees are, but have not heard back as yet. Here is the email address for EBSQ– info@ebsqart.com
