I have Discourse set up but it’s not at the domain/subdomain it will go live at. I’m still thinking about the choice of subdomain. Now that I’m starting to configure things, I’m wondering how much changing the domain/subdomain is likely to break things. Should I hurry up and get Discourse in its forever home before I create too much content and configure settings, or does it not matter because the change of domain is trivial?
