@suryo@mas.to
Welcome to the federated network that is this Fediverse. :)
Ideally you only need to create one account on one server (which ideally has a community and the moderation style you like).
You can communicate with people from other servers via this network, you only need to give the full username (in my case it is @ trinsec @ qoto.org, without spaces). It's just like email, it doesn't matter who your emailprovider is, you can send them an email regardless!
There are a few exceptions, of course. If a server blocks us, then we can't communicate with that one. Which is a shame, but hey.
As a rule, Qoto doesn't block servers, so we're one of the most connected servers on the Fediverse. Some do block us because of precisely that, but you can't please everybody.
If you're happy on mas.to you don't really need to move over, unless you like the extra features Qoto has to offer, of course (which you can read in the about page of our server).
