A small Doubt About Sign Quest.

[Trapper]

I am Doing the Sign Quest Thingy.
But Can any1 tell me which is the npc in the sign quest that grants allegiance Points?
Those who have done it might know about it.
As My Friend has done the sign quest and didn't get his allegiance point.
So is there any custom npc in the sign quest?
To Which I must have to talk for it.
