Can't wait to hear about certs! Never had paper ce

Can't wait to hear about certs! Never had paper certs before and curious how that will work if we get to redeem into common. Mail them in then I get xx amount of shares at whatever the PPS is the day received. Would be smart to hold and try to redeem at the bottom PPS of all redemptions pushing down PPS?? Just wish they were not paper. Oh well, we got em boys and girls!
