Thanks for the feedback! Right now the site is completely free and will remain that way for students. The next release will include a variety of improvements aimed at teachers, and we plan to incorporate a freemium model of sorts that allows teachers to use the current feature-set for free for a set number of courses, while paying for unlimited use and the more advanced features. As for marketing, we plan to meet with a few teachers in the NYC area to get a feel for what they would want / need and then promote it through schools in the area. We feel that teachers are becoming more and more familiar with the feel of web applications, especially those recently into the profession. The key for us is to create supporters out of this demographic and work from there.
