hey, still learning BC myself, but i know you should not have to change the "0.0.0.0" part, just the port. and you would only need to change the port if someone else on the shared host was using BC.
ya, thats an idea i was putting into the core opening of the door, but doesnt really solve my switch issue. just cant figure out how to make it become a different one each time without it messing up after a few lever uses.
