I've thought about it a few times. Now seeing that Tom agrees, it's a first step. But I still think about everyone I've played with... and well, although I do not mind to lend my characters for the idea of third parties, I think if everyone thinks the same way.
Imagine write something about, for example, Atanamir or Echtelion... just to discover weeks later that they're pissed off. But, if it's all for free... more people can try and compile something... like... "Life, Death and Intrigues in the Old Continent"... I'm terrible with names...
