Actually, I'm just trying to understand what are these "problems" we are talking about. Afaik, if you have a problem that may only be fixed by Talad and you ask the help of a GM and the problem isn't solved because that particular GM didn't "felt the need" to report it to Talad, you can try to report the problem yourself, to Talad directly.
What I understand from this thread is that Zanzibar suggests a second leader of the GM team, and I don't really see the point of having 2 leaders.
Your responce shows why this position is needed.
Your answer is outstandingly clear. What is my "responce" showing? I was just asking some questions about what this Liaison possition means and who and how should be the person in this position since the post isn't very clear. And, of course I was pointing out that this whole thread started from a false assumption on how the GM team works.
And, btw, trust me, I doubt that if a player has a problem and submits that problem trough a petition or talks directly to a GM, that problem will go ignored.
Want to invent positions and to create beurocracy? I bet that will fix problems alot faster

[yeah, this statement is ironic]
So, right now the thing works like this: I have a problem, I go to a GM, the GM ignores me [not likely but let's asume that], I go directly to Talad.
With the Liaison position, the situation will be like: I have a problem, I go to a GM, the GM ignores me [not likely, again], I go to the Liaison guy, the Liaison goes to Talad.
Besides, starting from the presumption stated in the opening of the thread, that the GM team leader, and the whole GM team are not impartial, what will be the guarantee that this Liaison person will be absolutely impartial?
