Do NOT use the 'acr' block for any other reason.
Why? Because this block stops any future printed or email notices from being generated for that customer for holds, overdues and lost items. Any unreturned items will go into Lost status 60 days after they were due and the customer’s account will be charged accordingly. But they won't ever get a notice telling them that.
If the customer has phone notices, they will still receive notices for holds and overdue items. But if those overdue items go to lost, they will not receive the final overdue or lost notices because those are always sent by US Mail regardless of the customer's notice setting.
