Bukkit

A Waypoints extension that adds functionality for Sign Waypointing
Requires 1.2 Waypoints. (May work on 1.1 but I doubt it.)
Make a sign reading:

Waypoint:
<destination name>

And it'll tp you there!

Permissions nodes:
waypoints.signs.create
waypoints.basic.go (and / or) waypoints.signs.go (either works)

When teleporting to a chunk that has not been loaded yet sometimes you will fall through the earth. Just retype /wps go <yourwaypoint> before you fall to far and you should be fine.

You may end up having to recreate some waypoints due to some code that ended up getting auto formatted in a earlier version that I did not catch, sorry for the inconvenience, waypoints locations may also not be correctly positioned in newer versions of craftbukkit as opposed to older versions for some reason.
