Use Taskbarn to Track and Manage Projects Online - Collaboration Tools

Lifehacker: "Taskbarn covers the basics of project management, including assigning due dates to tasks and marking parties responsible for completing them. In addition to the standard tools, each project is set up with a unique feed. Updates to the project can be published both within the Taskbarn feed and to an external Twitter account. Each feed update can be given a file attachment of up to 10MB—handy for tossing in pictures and voice messages to keep a group posted on progress."
