The Portal Administrator can enable e-mail notification about membership requests. With this functionality enabled, members would receive an e-mail notifying them when their membership request is either approved or declined. You can do this by creating a Scenario based on the Membership Approved and Membership Declined events, which are generated when the Community Leader accepts or declines a membership request.
If you only need a simple e-mail notification, you can use the ATG Control Center to enable membership requests by e-mail, using the following procedure:
- Open the ATG Control Center. 
- Select Pages and Components, followed by Components by Path. 
- Navigate to the - /atg/portal/admin/CommunityPrincipalFormHandler.
- Select the - sendUserEmailproperty and set the value to- true. Note that by default this property is set to point to the- sendUserEmailproperty in- /atg/portal/framework/Configuration, so you could also set this property in the- Configurationcomponent.
- Specify text strings for the - requestEmailSubject,- preMessage,- postAcceptedMessage, and- postDeclinedMessageproperties.- The - requestEmailSubjectstring appears in the e-mail’s Subject line; the- preMessagestring appears before the community name, the- postAcceptedMessagestring appears after the community name when the membership request is accepted; and the- postDeclinedMessageappears after the community name when the membership request is declined. For example, when these properties are concatenated and the community name is included, the message might read: “Your membership request for the Tennis community has been approved.”
- Make sure the - emailerand- emailSenderAddressproperties are set properly.
- Click Save.
