TumbleCube is a collaboration platform that uses a task-oriented project mailing list. It gives your team a single email address. When a member sends email to the group, everyone gets the messages. Best of all, when a new task is identified in the emails, with a single click, you can add it to the project and assign it to the right user. No more sticky notes or logging into another task management system. Also, we keep all of the emails, including attachments, so you don't have to clutter your inbox with them.
