Email Double-Check

Email Double-Check allows administrators to add a second email address field in specific profiles. The extension confirms that the email addresses in both fields are the same, reducing the likelihood of mistakes in the entry.

Since the extension must be specifically allowed for each profile after a general in-site installation, it can be enabled for specific profiles without affecting others. 

Notes for Installation and Usage: 

After normal installation, check the Settings for each profile that you want to use Email Double-Check on. Under Advanced Settings, check the box labeled “Require double-entry of primary email address (if field exists)?” in order to allow Email Double-Check to work on that profile and save changes.
