Need discourse tips

I hope this is the right place to get support with Discourse. My first question would be how to tell Discourse that I want to see other people’s names and not their usernames.

Currently I’m concerned everyone will see me as “ahardy42” instead of “Adam Hardy”.

There doesn’t appear to be any option in the preferences for this.

@Aamirah-WeAll including you in here just in case you already know the answer.
