Duty Roster is simple and easy to use. Originally designed to be used in a Real-estate office where the agents shared phone-answering duties. Duty Roster can be used to establish weekly rosters for Class Room schedules, Hockey Team Ice time, Events, and even a roster for the kids to do their chores. Make a Roster, Save it for later edits, Print it and post it on the frig, assign Duties randomly or sequentially, set deferent time schedules for each week, Add Notes. It s really simple -- make a list of Names, Events, Activities, Chores, then drag-drop them into the appropriate time frame (or randomly apply them), save it, print it, or recall it and change.
