Trello

Trello is an excellent site for organizing and collaborating on projects w/ others.  This is done through the use of on online board (similar to a whiteboard) that is filled up w/ tasks.  These tasks are arranged in cards and can be used in real-time w/ others.  These cards can have multimedia content such as audio and video embedded into the card.  This is ideal for working on projects and having others see view/collaborating.  Everything is backed up and stored online and very easy to use.
