Hi folks - I have a few questions that I promise I tried to answer myself via search, but I can’t get clear answers:

1. How does Lemmy handle identical usernames registered across different instances? I assume Lemmy isn’t calling to every instance to check usernames on signup

2. What considerations are there when determining what instance of Lemmy to create a community on?

3. Has anyone deployed a Lemmy instance on Azure? I’m looking to go down that path
