Sam, I think you misunderstood my post. I did not say I was talking about “here”.
I was talking about a different place entirely, that uses Discourse. (I am not a new user there, either, BTW.)
So, I was asking about a new configuration option in the generally released software.
(ETA that I now notice you’ve changed the title of the thread and of course it does not reflect what I was actually enquiring about. I’ve edited it.)
