Considering the state of the Forum (and the Mod in general) I doubt anyone would really notice if you posted the coordinates... the only thing stopping you is the goodness in your heart not to ruin the search for others.

Yes, the mod is in anarchy. There is no central force of control after Grievous left the wiki a while back and Mevans disappeared. Do whatever you want. Post the coordinates to Meneltarma. Ask for Gandalf to be added.

Seriously? Is there a ban here for sharing coordinates from hidden places?

And that the creators treat it as spoiling the fun for others? On what basis?

As if it's stupid, because to remember the coordinates, it may take a while, and those who want to search on their own will do it themselves, and those who don't want to search through the entire map, let them have a shortcut to it.
