This question is vaguely related to the previous post (Endorsement of Principles by smaller / grassroots organisations).
When organisations endorse, do you suggest a link from the organisation site back to the Principles site?
E.g. with Creative Commons sites, usually you put the CC licence at the bottom of site pages. I’ve also see members of https://www.coops.tech/ carry the CoTech logo at the bottom of their sites.
