I am mildly disturbed by how much better you are at Discourse than I am. Don’t tell Jeff!
I’ve added it to my to-do list. It’s not a launch-day feature. And it’s worth taking some time to think through implications. But most the implications I see now, I like.
A minimum implementation might just give users a text box where they can list affiliations, and show that below their name and avatar on project pages. Maybe add a search box on project pages that filters people displayed by name and affiliations.
