During these days I played some matches on the BfW multi-player (MP) server. Before these matches I never played BfW in MP mode, but only in single-player mode. I still consider myself a beginner, although I'm making some progresses with my gaming/strategy skills.
The MP game mode functions in a pretty straightforward way: within the game interface you choose "multiplayer" and you are faced with a window for choosing which server to connect to (official, custom, local…). The "official server" brings you into a lobby room interface which displays all the people connected to the servers and all the games that are currently set up. Moreover, it allows for some actions (such as joining, creating or observing a game, filtering the list of games, simple chat with other people).
