From what I've seen, handbooks are a bit of a grey area - probably because locking them and forcing the creators to repost them from scratch simply because someone had a question would be onerous. I know for instance that I've gotten permission to update my old handbooks past the window.
I don't know if that applies to anyone posting in them or just the creator but I'm sure Glyphstone or one of the other mods can provide clarification.
EDIT: I just took a closer look at your avatar - is that a barbarian hugging a troll?
