Members of the SuTree community can link to, tag, and categorize lessons in the form of videos, Flash presentations, PowerPoint files, audio-only files, and more. Community users can provide content ratings, comment on lessons, and send lessons to friends. Fans of the website can add a SuTree search box widget to their website or blog.
