If your portal uses the manual approval membership policy (Allow requests for membership and notify Community Leaders on the Community Settings page), then membership requests will be sent to the Approve/Decline Membership Requests page. The Community Leader uses this page to either approve or decline membership requests.
Log in to the Community Administration Pages.
Click the Community Users tab.
The Community Members page opens.
Click membership-request.
A page listing all pending membership requests appears. Each membership request shows the name and e-mail address of the person requesting membership.
For each person requesting membership, click later, approve or decline, then click Update. You can also select all pending requests at once by clicking one of the all later, approve all, or decline all links.
