This PR is ready except it fails to resolve {reset_password_link} only for the New User Registration template.The URL is generated for resetting the password but on clicking it gets redirected to http://example.com/wp-login.php?action=lostpassword&error=invalidkey. I'm not able to figure out why the key is invalid and have requested @ravinderk to look into this. Once this is fixed, the PR will be ready to merge.
