Hello, I'm trying to build community for customers, single customer may have a dozen or several dozen members, how can I group them to see the company context in admin panel? I had considered to use: - groups - but it's non optimal to create so many of them, because groups have individual permissions per each forums - custom ranks - but it's not practical, especially I don't want common members to see the company context of others - custom fields - sound's most reasonable, unfortunately I can not show this field on the user list in admin panel any better ideas?
