The addon allows you to select a destination from an option menu when opening the world map. The option menu contains all Zones and local POI's. The POI's are the same as the requirement for each step in the Explorer Achievement.
This addon can assist you with, getting your Explorer Achievement, as well as pointing you in the right direction to go anywhere in Azeroth or Outland that you wish to travel to. Point Me will become increasingly useful with the release of World of Warcraft Cataclysm and with old world flying.
Point Me is a fire and forget addon, that once you have selected you destination, all that it required of you is to start traveling in the right direction. Point Me makes use of the TomTom addon, by displaying a Crazy arrow, Distance to destination and Estimated time till arrival.
Note that the TomTom addon is required for this addon to function.
