I've thought about this a little.
Baring the name Tol-in-Gaurhoth, there is little else Tolkien related in most WW games. But that is no defence for my own part.
I'll give some extra thought to this today and get back to you with some ideas (if anyone else has any, they are welcome).
I have had a better idea for the secret messaging, however:
When a player has been kidnapped or whatever, they can set a secret message in:
a) Their signature (again, secret link in full stop)
b) A PM to me with a coded message. Or
c) Again with a PM to me, an advertisement to be placed in the newspaper the next day.
I'll give some more thought into getting it more Tolkien related and get back to you as soon as possible.
