Yes, this is possible. You will need to give them "delegate access" so they can deposit on your behalf and complete the deposit. To do this within Elements follow Menu>My account>Manage delegates and select the user you would like to delegate access to. Delegates will need an active CRSid and Raven login to access Symplectic Elements. This user will now be able to impersonate your login, update your Elements profile, claim publications and submit articles on your behalf.
If you have a research group it is also possible to delegate Elements access for all members of the group to one administrator (for instance, a personal assistant, secretary, lab manager, etc). If you do not have this level of access and need it, please email firstname.lastname@example.org to request delegate access for your group.
