(Sorry for the late reply - I'm on holiday with patchy web access.)
I'm so glad you enjoyed it. When I received the list of characters you wanted to see, I was first considering writing Minverva (who is my favourite female character in HP), but then I thought that she will probably be quite well represented in the fest, and decided to give Poppy a shot. It was an interesting exercise, because I didn't quite know in the beginning where I was going with her. So it's good to know that the characterisation worked out for you :-)
