Owing to the amount of interest I received about A New Kind of Graded Reader,
I have started a mailing list at
http://groups.google.com/group/graded-reader
and also I plan to make my code available at
http://code.google.com/p/graded-reader/
If you're interested in the idea applied to any language (not just NT Greek) please join us.
The original post was in the categories: linguistics language_learning graded_reader but I'm still in the process of migrating categories over.
