Barbara used to be the Tarot editor for Llewellyn until some years back.
Then she left Llewellyn and she is know an independent author and writer, even if she still work closely with Llewllyn as an external consultant. She attended that meeting in that guise.
As for the "leaking" I can assume it is part of both.
Barbara has published her "leak" on the Llewellyn website (but in her blog where the content is hers and her alone). But I can quite picture her sneaking a few pictures during the meeting, folowing an impromtu feeling. And most certianly nothing that was in the meeting room was intended for the final public, nor her pictures and comments have bene approved by marketing.
So yes, she is joking and she is not
