There may be a scenario where multiple people like testers, developers, and deployers might be involved in a request fulfillment. For that, the progress of the request has to be constantly monitored by them. However, they cannot be given full privileges to access all requests associated with a site/group/department. This script will automatically share the request to the groups assigned to Tasks associated with the request. 

This can be also configured on 'Request custom menu' so that the action can be invoked when it is required. 

The Script is available here.
