I don't know if this is something unknown or not. I also didn't know if I should put this here. I figured I would, though, because it really helps out the people in the frontier. This really is nice if your village or claim is far away from town. Anyway, I found that on smp5 (I think) or maybe any server (I don't know), you can set your spawn in the frontier and then go to town. After you are done in town, instead of going back over land, you can go to the end and then exit and you end up at your village instead of back in town. This is nice because you pretty much cut down on half the time.
