How does XMPP work? I'm looking at Jabber's website and apparently some clients are both clients and servers at the same time or something? It's quite confusing...
Are spaces or multi-channel groups (like discord) a thing in xmpp? Which clients support that on iOS and Linux and etc?
Is Movim a client or a server or what?
Are groups hosted in the server of the user who created it like on Matrix or what?
Any easy tutorials I could send to my discord friends?
