Hi, I am currently living with 5 Room Mates and we all play RuneScape. Up until now we've been playing on the Official RuneScape Servers, but we are considering an RSPS to play all of the Game including Members Worlds without having to pay $14/Month per person. We all have the same IP because were Room Mates... Is there any Rules towards how many people can play from one IP Adress? We do not bot and will never ignore a Random Event... Hopefully it's allowed. : /
