To submit work electronically to the moderator, you need to request the four-digit OCR mailbox address, e.g. ocremxxxx@ocr.org.uk from the OCR customer contact centre.
As soon as the unit(s) are claimed on Interchange, email the moderator to give them login details and instructions on how to navigate around the site.
It is important to send the moderator this information each time you make a claim.
