Update: Partial solution: Tell your users to profile > settings > Select the group title you would like to display > select from drop down. This makes a badge show up beside their name. I don't know if the badge will auto upgrade as they gain more reputation.
I updated some rules and restarted the forum but they don't seem to apply to existing users? Am I doing something wrong?
For example, I have a rule where if user has more than 100 reputation add to group ,veteran, but the users with over 100 reputation don't get the veteran badge.
When I look at groups, the user is assigned to that group, but I don't see the badge on the forum.
Thanks for reading.
