So I think some people were discossing this in another thread, but I didn’t see a suggestion for it. Anyway, I think you should be able to go into settings, and under title, make a custom one, that needs to be verified by staff. It should probably only be for regulars, to lower the rates of innapropriate title.
Discourse is a forum tool which these forums happen to be using, searching DISCOURSE on Google should answer your question, you’ll see the discourse forum page looks almost the same as here
