Continuing the discussion from Heavy Hitter Sports: Pre-The Legend Lives On:
tl;dr: This turned out to be vastly more complicated than I’d expected. I’ve reached out to the Discourse support team about it.
There’s a 3-day grace window in which you could have changed your username. (Look! A new configuration knob I’d not know about…
*sigh*) After three days, it prevents all users from changing their username.
Ok, easy! …I can just change that setting to a big number and then Mark can changes his . . .
One’s username turns out to be very deeply stapled to your identity in the system. If you change your username, you disown everything you’ve done. Your posts would remain written-by the no-longer-used “markhoch”, and the new “hoagie” (or whatever you changed to) would be a new user who begins anew.
So now I see why you’d want that three-day-window kept small; Because of the train-wreck-disownership I described above, you [as a new user] don’t want to go very far before you disown everything you’ve done.
For added complexity, I don’t know what that would do to the subscription system either.
