Can you add an option to put a question mark by the pledge amount, so the person sees he has to give something but without a suggested amount, this will be usefull by מתנה לבימ"ד and by different פרנסים that we want to send a bill, or it should be included in a statement with other charges, and its even better than $0 pledge because $0 = $0, but $? = mystery amount.
