Thank you so much, everyone, for entering the competition. I really learned a lot and appreciate that you took the time to feed back to me.
These are the winners from the people who kindly commented on my blog post.
Winning two audio codes each: Gillian Webster, Katrin NicDhaidhild, Julie Beaghan, Dianne Thies, Theresa Lynn, Louis Antoine, Claire Serafin, Fiona Wilson, Jan McKay.
Winning the grand prize of all seven audio codes (so you can get the whole audiobook series): Gail Staggs.
CONGRATULATIONS, all! Dianne, Jan, Gail, I will PM you the codes tomorrow via FB. (It's a bit late now and I'd better do this when my brains are less fogged.) Would the other winners mind emailing me at firstname.lastname@example.org? Thank you! I'll send your codes by reply.
