To join a FragLive or Free server you will first need to have both the game and GamerClient installed on your computer.
If you want to join a FragLive server, you must also ensure that you are a CA$H member and that you have sufficient balance on your PlayAll account.
By simply clicking the 'connect'-button on the server you wish to join, either via the GAMES section on the PlayAll website or via the FragLive/Free Server function in GamerClient you can start playing.
