You have always been able to add tasks to yourself, another employee or a group that can then be collected by an employe in that group or assigned by the manager.
We have now added a new way to add a task for everyone in the company, a task to everyone in one or more groups or a task for a selection of people. Basically this means you can add one task to more than one person. It might be to read the newly drafted Company Handbook or sign off a document or submit expenses.
To use the ToDo module it should be turned on in Admin > System Functionality > Set Functionality Required and the tasks can then be added by going to Actions > ToDo's > ToDo Menu.
