You may want email notifications to be preselected by default for certain actions performed within a group - adding a document, for example or amending a ballot. To review or change the settings for a particular group:
go to the Manage Existing Groups page (http://www.mysite.org/apps/org/workgroup/admin/workgroups.php)
find the group of your choice
click: Modify
find this section: Email Notifications There is a list of checkboxes that represent different actions that can take place within the group (add/edit events, etc). If a checkbox is marked, the email notification checkbox on the corresponding form (Add Event, Modify Event, etc) will be selected by default. Any user completing the corresponding form can unselect the email notification checkbox, if appropriate, on an individual basis.
review the configuration and make any desired changes
