How to remove an email address from a client account?

Here are my step-by-step instructions about how to
Step1: Client ->Client Account-> search for the referring client's account-> Click Edit under the action section.
Step2: Click Edit at section Basic Info
Step3: Remove the current email address and enter the client's actual address or a dummy address for internal use.
Save changes before leaving this page.
Note: After the email address is updated, the new credentials for this client are the client's new email address plus the password you received from the previous invitation.
