Macro to enter and exit battleground

[lans83]

/run
AcceptBattlefieldPort(1,1);
AcceptBattlefieldPort(2,1);
AcceptBattlefieldPort(3,1);
AcceptBattlefieldPort(4,1);

I use that macro I found from a post a while back. Not sure what the difference between the port numbers means, but it seems to work for me getting into the BGs. I've only hittin it once when the first window popped for my team to enter. Haven't tried it yet to exit the BGs, as I've only run them a few times since multiboxing.
