A to-do is a task that has to be completed. It is always associated with a Planzone project. It can have a priority or due date and be assigned to one or more project team members. It can also be left unassigned, which means that it can be completed by any project team member. 

Each project has a list of to-dos. To-dos can be organized by activities. To-do assignments across all projects are also listed by date and alphabetic order on a Planzoner's Home and My to-dos pages.

To-dos are a collaborative instrument and any team member (excluding guests) can create, delete, assign or edit to-dos.
