Admitto accounts for people who have left the Chemistry Department require regular renewals which have to be approved by a PI. This is to ensure we are only giving accounts to people who need them for departmental work. PIs can contact the computer officers to have accounts renewed, but may prefer to grant the renewals themselves using the Delegated Admitto Account Renewal web page at https://apps.ch.cam.ac.uk/dar/ . They can also nominate another person to do this on their behalf.
