Should I change my domain before launching?

Using Memberstack 2.0? There is an updated version of this article here.

TLDR: Nope! The testing domain in Memberstack has no effect on your finished site.

Let's say your site has two different domains: one for testing and another for your "actual" domain.

You do NOT need to update the testing domain. Memberstack asks for a testing domain so its validation bots can find your site and help you avoid mistakes.

You could completely remove the domain from app.memberstack.io and your site would continue to function.
