The example you provided was actually one instance.  Lynn had written that you know nothing of Skyreach Online having been an MMO in the real world.  I can't quite see how you got to the interpretation you did, admittedly.  The opening sentences of the introduction in the recruitment thread also made it fairly clear that memories of the real world aren't really present in the character's minds.  It also implies later in the introduction that the mention of game mechanics and terminology in the guidebook don't make a lot of sense to the characters due to the fact of them perceiving the game world as their real world.  (or at least that's what I got out of it when Lynn wrote that the guidebook explained a lot of weird things that didn't make much sense)
