It was the Write Guide
http://www.writeguide.com/
It is very inexpensive to try it out, so I recommend you do this before deciding that it is not worth it based on my opinion.

My impression is that the tutor was giving DD examples that were totally unrelated to the piece she was writing, occasionally way above her level of comprehension - like pluggin in the text that the tutor already had prepared for someone else.
But I really encourage you to try it out before forming your own opinion . It is like $50 a month or so, and the student can write to tutor daily.

Since you are familiar with both :Caesar's and Word within..., which one do you like best? Caesar's seems to be more clear to me for some reason.
DD is doing Word within... at school.
Cym, I am awaiting eagerly to hear from you...
