How can I turn my PVP mode off?

[ssl228]

PVP flag:
I'm a newbie to this fantastic blue server, but i may made a mistake by giving my book to the Priest of Discord and turned my status to PVP, until a kind player tell me what's going on. So i don't know how to get back to the Blue name.
I've petitioned to GM by posting a thread in the specific column but i don't know if it's the right way to go...
Is there any way out? Guys help me...please......[You must be logged in to view images. Log in or Register.]
