A task is any activity for which you want to track time. Tasks can be high-level (ex. Hrs Worked) or very specific (ex. Widget Testing). It is entirely up to you.
Each project has its own set of tasks. Click on Settings then click on Projects. Click on the name of the project that you want to edit. Tasks are listed under the Project Tasks section.
Looking at the task list, click Add Task. Fill out the task information then click Add Task. To add the task to multiple projects, select Yes for Copy Task to Other Projects then select the projects you wish to copy the task.
Looking at the task list, click Edit on the row of the task you want to edit. Update the task information then click Save Changes.
Like Projects, tasks are never completely deleted or removed. Tasks can be archived. Users are not allowed to enter time for archived tasks. Time already entered for that task remains.
Looking at the task list, click Archive beside the task you want to archive.
Recover Archived Tasks
Go to Settings -> Projects then click on the name of the project that you want to edit. Looking at the task list, click Recover beside the task you want to recover.
