sharing breast milk??!

would you ever give your baby donated or donate your extra breast milk? Personally I would it if it's available to me, fed is best but if it's an option I'll gladly take the option, doesn't have the exact same benefits of a mother breastfeeding right from the breast because of the way the Body Works it gives the baby exactly what it needs at that time but it's in my opinion still a step up from formula so I would do it and where I live there is programs that do it and they test the milk and test the mothers to make sure it's completely safe. So would you use another mothers donated milk or donate your extra milk?
