To create a notification, click on the Add button at the top of the table. A window will appear that will allow you to search for the calendar you wish to receive notifications for. Click on the Add button next to the calendar and it will be inserted into your notifications list with the default settings.
Once inserted, you may configure a name for your notification filter. This is simply a friendly name used only on this screen so that you may quickly identify filters in the list. You may then configure a category, and title filter (case insesitive). If an event is added or updated in the calendar that matches the criteria in a notification filter, you will receive an e-mail notification.
Note that the display format of the e-mail notification will differ based on your Theme setting.
If an added or updated event matches multiple filters that have the same e-mail address, you will only receive one e-mail. For instance, you may have one filter that checks for the category of Meeting, and another that checks for any event titles that contain 'meeting'. This way you are sure to receive notification of meetings added to that calendar without receiving duplicate e-mails.
