To join (well the way I do it) is press on the things at the top saying server 1 server 2 rust and teamspeak, and press server 1 or 2 for arma rp click rust for rust I recommend joining teamspeak BTW. Once you have done that go to your recent servers add rpuk to your faverouts and then everytime you launch the game on the battel eye hub press servers and then go on favoriouts and finished! hope you enjoy you're stay BTW i cant spell :/
