I can know I have a citation for this, but I have to go offline RN. If interested, I will come back in a few hours with info? My recollection is that she's not all OMG, YOU'RE RAEPING MY CHILDRENS! like some, but more sort of concerned about it.

There is a list somewhere produced as a result of some of the recent wank on this subject, of a whole bunch of authors and their feelings about fanfic, I just don't have time to track it down right this moment.
