Thanks for your observation! It confirmed my suspicion that maybe groups are the feature I’m going to have to use. Manual attribution is not a big problem as indeed, we are very involved following our users closely and being familiar with their situations. With groups, I can have non-moderators with the rights to add/remove people from groups, right?
And you’re saying « titles » would make it possible to display the groups a user is in, therefore making them « badge-like »?
