I'm going to make this clear now: just because you have been invited doesn't mean you HAVE to join. If I or someone else has invited you and you don't know who she is or absolutely hate her please do not write nasty comments. As you have probably guessed I am a MASSIVE fan of her work. You can add related projects but only change the pic if it's about Cressida or her books.
For those of you who don't know she has written; The How to Train your Dragon series and the Wizards of Once
P.S The movies and series are NOTHING like the books!
