From the sounds of it, it sounds like you are more asking if GMing a scenario prevents you from playing it, which is a solid no. What TriOmegaZero said:
so here's my first question, if I am running the game and qualify for the rewards from the adventure as a GM, is my (same)character able to play that module then? or is she bared from playing through that adventure then as a Character? for example say my Almut wants to play 'the Frostfur Captives' and I have GMed it.... is she disqualified from playing it, or is she able to.. even though she has gotten rewards from it??
Edit: also will another GM need to Sign the Chronicle sheet for her to legally have access to the rewards if i GM the game she would have access to them in? just trying to make sure it would be done fairly.. planing on taking some friends through 'We b4 Goblins' on Saturday to introduce them to Pathfinder, possibly run through the rest of the 'We be Goblins' series if they like it... but with this info i am seeing about gaining rewards it has me confuzzled...
No character may have more than one chronicle for the same adventure. So no, Almut cannot play that scenario unfortunately.
is true of course but this is assuming you have applied the GM credit to that specific character. For example if you applied it to Rei UlSkadi, Almut could play the scenario, assuming you haven't played it as a player yet.
Also I don't think you have to have another GM sign off on a character sheet if it's from a game you GMed.
