If you're a Project Manager and your organisation has elected to use i-lign Timesheets, you have the option of being emailed Timesheet Notifications only for those people whom you have not assigned to the Project.
You can edit items in the Gantt Chart by right-clicking on their name and editing, or by changing their details in the Gantt's table columns. You can also change their planned dates by moving them on the timeline.
The Gantt Chart's table columns provide detailed information about items' planned and actual start and end dates, their duration, effort and so on. You can change which columns you see, and the order they are in.
