Could we have castle gates? Such as you have a gate made out of fences, and you have a sign beside it that says something like [gate]. I know this is possible, I was just suggesting we have this for castles, etc.
I wish Notch would have put pistons out on the newest update. We could've made gates out of those (but this would require pistons being able to push other pistons so you could get a wider gate (such as a 3 or 4 wide gate) which would be great if that could be implemented)
