@silverpill Good to know, thank you! IMO there should be no restrictions on the two domains – I use two subdomains for convenience reasons, but platforms should support two completely different domains as well.

At least in my opinion. The vocal opponents of split-domain handles say that a user's handle should tell you where their profile is hosted, and there are nuances around things like domain blocks.

But if you ask me, I should be able to set a custom handle domain in my profile settings. 😄
