Suggesting a prompt to staff or patron to update the messaging preferences if a new member is registered with no email/SMS number and the messaging prefs default to 'on', or if an existing user account is edited and the SMS or email contact info is changed. The lack of this reminder leaves many accounts with failed/unsent messages or pending 'print' messages. Also when an email address is added, notices are not sent because staff/patron may not turn on messaging preferences. There are a couple of old bugs about SMS / failed email. This might help with those. Related: 14964 23497 14590 14872
