Tasks are jobs, which you to do as owner of the task until a certain date. Owner of the tasks is depending on the selection the event date coordinator or the owner of the event. Avendoo® generates the tasks from the task templates, which you have created under Resources → Task templates and have added in the Venue assistant, the Room assistant, the Materials wizard, the Event wizard or the Event date wizard. Once a task is due, Avendoo® sends a community message to the task owner. If you change the event coordinator or the owner, the open tasks also change. The open tasks also change, if you change the task template assignment.
There are the mass processing functions Change status and Change owner for tasks. More information about these functions you find under Tasks: Mass processing functions.
