Working with Mac OS and using Safari: impossible to add/follow a member from hcommons. I think it will be useful to add an icon “+” or “ADD” on the member’s profile page and/or just next to the member’s name on the page list of members.
Are you logged in to Humanities Commons on Safari? I’m on a Mac too, and I just logged in on Safari and get this. As you can see, I followed you, so I now have an “unfollow” option, but I can follow others.
As you can see from Émilie’s profile (viewed on a Mac in Safari), there’s also a “follow” link right under her profile picture.
