A work is under CC-by-ND but author permits fan fictions
<p>A person posts an e-book on some web site and attributes it as CC-by-ND. Then he creates a public discussion in Vkontakte with the subject ”Post fanfics of %e-book's name% here“. Nevertheless, is it legal to post fan fictions in that discussion (without asking the author first)? To post anywhere outside of that discussion?</p>

<p>It's probably legal to post them there, it's probably not legal to post them anywhere else.</p>

<p>A copyright owner is free to grant multiple licences over their work (except that they can only grant 1 <em>exclusive</em> licence). In this case he has granted a general CC-by-ND licence to everyone. He has also granted a licence for derivative fan-fic but only if it is posted where he says.</p>

<p>At least, anyone sued for copyright breach would have a very strong defence along those lines.</p>
