How do you improve on Moodle?

Try something different. Perhaps.

Now comes ATutor.

"ATutor is an Open Source Web-based Learning Content Management System (LCMS) designed with accessibility and adaptability in mind. Administrators can install or update ATutor in minutes, and create themes to give ATutor a custom look and feel. Educators can quickly assemble, package, and redistribute Web-based instructional materials, easily retrieve and import prepackaged content, and conduct their courses online. Students learn in an adaptive learning environment."

Devil is in the details.
