Official briefings are still signed on paper but read & signs are now done through CEDAR. I don't remember what CEDAR stands for. Technically, I think we are supposed to check it before every shift but if something needs to be done then the way my area does it is that they'll put a strip that says, "CEDAR" in the on position list so when we go to run the list, we'll know we have something to read & sign (digitally).
