Hi i am a new i how setup server in ja plz say me thnx
Check out the hosting options in JKA MP. Theres also a server forum here, check that out too. It would probably be best to just simply buy/rent a server. I hear you can get one for like $29.99 a month, or something.
What kind of games do you want to host? Serious server with competitions and stuff or just a little one so you can play a quick game with friends?
