new str[128];
		GetPlayerName(playerid,pname, MAX_PLAYER_NAME);
		new RandR = random (8);
		if(RandR == 1)
		{
			format(str, 128, "Hello, %s!", pname);
			SendPlayerMessageToAll(0, str);
		}
		else if(RandR == 2)
		{
		    format(str, 128, "%s, what's up?", pname);
			SendPlayerMessageToAll(0, str);
		}
...

this should work
