Chamu makes it easy to communicate with your notes and files outside of email. Chamu allows you to manage and collaborate on the fly.
To be honest, I didn't think I'll be still using it to this day today. This tool has proved resilient, simple with the UI/UX are one of the simplest with little to no learning curve. The way you invite colloberators or affiliated members to view, comment or edit makes it one of the best implementations EVER. All respect to the team behind this.
