You can contact the relevant School secretary and request the CRN number for a specific module. The CRN number is a five digit number that uniquely identifies a module. Once you have obtained the CRN number, email it to email@example.com requesting to be added as a lecturer to the module. If you want to set up a module in Moodle, which has no set CRN number (e.g. for training purposes, for sharing information with partners), then briefly state the intended purpose of this module in an email to firstname.lastname@example.org.
