When a patron adds a second email address or telephone number in Vega Discover, it is stored in a separate field in the Sierra patron record. This can be misleading because Sierra notices are sent only to the first email address or telephone number on the record. Any additional email addresses or telephone numbers are ignored for notices.

Until Sierra notices support sending to multiple email or telephone fields, we want patrons to be able to update their existing email address or telephone number, but not add a second one.
