This question is from 2018 and maybe things have changed.
- I have “full name required” checked.
- I disabled “enable names: Show the user’s full name on their profile, user card, and emails. Disable to hide full name everywhere”
- I let “display name on posts” checked - but they are not showing anyway due to the above option disabled that takes precedence I guess.
From this point, can a user have her/his full name displayed with her/his username when posting if (s)he decides so? Or is that a system-wide setting only?
