From the Members section of your administration interface, you can find the list of users who have requested access in the dedicated tab.
You can click on Confirm or Decline for each of these requests.
Best practice: Check the identity of the user. If you do not recognize the email address or the first and last name, do not accept the request. Do not hesitate to communicate this good practice to your employees!
Click on Submit to change the user's status to Active. The user is now part of your community!
You'll find them in the list of members (tab on the far left of the image).
You can set up your notifications so that you receive an email each time you request access.
