We have spoken to Michael in the past about role-playing and I have to agree with him on this point:
We've looked at many role playing sites for the likes of Harry Potter etc, and in general they're really not very pleasant to read. It seems sad that the 'players' do not respect the characters that the author takes so long to create and so many times they have the characters doing unbelievably violent things, or seek to take the characters well into adult rated romantic behaviours. Michael does not want this to happen to his characters, especially Josh and Sophie who are only teens.
For those very pertinent points of concern and out of respect for his wishes, we will never feature, nor endorse role-playing of the characters on this site, or any other.
I hope that explains it well for you.
