This is a slightly interesting one that I'm not super sure how to describe. On my notifications page, I got a new follower that seems to have their gmail address as their username. However, as the page is loading, it briefly shows as [email protected], which seems like a good thing to have! But then after that it fully loads and displays their gmail address once again,
make a test account that has an email address as its username follow a world go to that world's notifications and hit refresh, but then stop the page load before it finishes to see it displayed as [email protected]
There is no code as such on World Anvil - that looks like a browser/plugin thing ;) ... 100% sure I never even thought, let alone coded anything like that :D
