When you log onto this portfolio (https://portfolio.ncl.ac.uk/) you should see listed:
Personal Tutor (students on taught programmes)
or
Supervisor(s) (research students).
If your tutor information is incorrect: please ask your School Office to change your supervisors on the SAP administration system.
Once that has been done the updated information will normally feed into ePortfolio on the next working day.
Your share group 'My Tutors' (see 'Sharing' icon) will be automatically updated to reflect that change and your supervisors should see any blog entries that you have elected to share with 'My Tutors'
