Classlet makes handling assignments easier for teachers and students. We've got a whole bunch of features that most of the competitors don't have:

1. Students never need to register, only the teacher does 2. Students never even need to visit the site, they can do everything through email 3. Anything that can be passive, is. In most other systems, you constantly need to check if you've gotten a grade or if an assignment has been posted. We don't make you check, instead we let you know by email (and working on other channels too) 4. The teacher can do all of the grading within the web browser. They don't need to download a hundred individual doc files and open each one in word. Instead, they do it all from one page. 5. We keep a timeline for each student for each assignment. You can see any submissions they've made, if they submitted late, if they submitted an older version, then a newer version (teach has access to all versions), we mark if it was submitted late, etc... 6. And we try to make it easy to facilitate a discussion between the teacher and student.

Those are 6 of quick things off of the top of my head that set us apart from the competition.

Thanks for the feedback.
