Recording a Member Change
When a career event (such as a promotion, or change in title, or change in position) occurs, you can record that along with the date of the change. This is valuable for a history of the event.
You can change position, title, station, radio designation (call sign) and/or status, e.g. on leave.
Make the change, e.g. add a new call sign or change a call sign.
A history of changes (e.g. leaves of abscence, promotions) is maintained.
