I worked with Christina Hughes. I swear, everything she did was perfect and she left me feeling really good about the finished piece as well as the publication it went into. Our interaction was so short but she accomplished everything that needed doing in three, maybe four emails, and was unfailingly polite and respectful.
[edited to add] OMG, I'm such a dumbass! I just looked up the emails to see how many there were for sure and realized it was a different publisher entirely! It was a different educational material publisher, Cambridge Media Group.
Anyway, I'm glad you had a great experience and it's even good to find out that multiple educational publishers are making use of useful content they find online and treating those who write it well.
