//this uder your game mode
SetTimer("message",60000,true);

//now this anywhere in script
forward message();
public  message()
{
new ran,mes[50];
ran=random(5);//no. of messages u use in brackets
switch(ran)
{
case 1:format(mes,50,"Use /help to view how to play on server");
case 2:format(mes,50,"Use /cmds to view commands");
//like this continue till no. of messages filled in brackets of random
}
SendClientMessageToAll(-1,mes);
}
