[LEARN] Misc: Presence Servers
Although most content in Janus is served and received much like a traditional web browser, it is the presence server that connects you with other users. It is through the presence server that you are able to talk, type, move and interact with others.
As you move from website to website, you'll find yourself switching between "presence servers", as any person who runs a website can also run their own presence server. However, if the room creator doesn't specify their own presence server, the Fallback Server listed under the Network section of the Settings menu will be used instead.
