I will need to understand how the different groups work here. I see some with @email@example.com or . Social or .me or….
@clarinette it's almost like with email. Some have Gmail, some yahoo or hundreds of other providers/servers.
Same here, some accounts are on one instance, others on another. But we all can see and talk to each other. (If that instance isn't blocked on yours or vice versa.)
Maybe check out resources such as https://fedi.guide/ 🙂
