==Description==
Scheduled Tasks are used to run routine site maintenance tasks as an alternative to server cron jobs. The tasks are defined in plugins in the task group. A number of task plugins are supplied and can be used as examples for creating other specialised tasks.

==How To Access==
Starting from the Administrator menu:
* Select {{rarr|System,Manage panel,Scheduled Tasks}}

The initial Scheduled Tasks list is empty so select the '''New''' button to get started. The screenshot shows the example tasks.

==Available Tasks==
The following screenshot shows a list of available tasks. Some are demonstrations, some are useful.

Each task has its own task related parameters that should be self-explanatory. For example, the '''Site Offline''' task only makes sense if the {{rarr|Edit Task,Basic Fields,Execution Rule}} is set to '''Manual Execution'''.

The other parameters are optional!
