Yeah. I noticed after I had already written this message that you had created several threads. Well, it's not bad to create separate threads either, but if possible I will suggest you to combine them in a single thread. As otherwise it will only become hard for others to find this author's work.
One more thing I need to tell you. It's opposite of this. You've created single thread for Fiona Piper and Aimee Allison, but I think you should keep them in separate threads. While the two have published together, and have even operated together in some stories, along with Domina Dixon, nowhere has it mentioned that they are different alias of the same author. In fact, my personal feeling is that they are all different. It's because of the quality of their work. Fiona is best of all, but Aimee is not bad either. Domina, however, is kind of a weak author.
