I'm very glad to say we have started to roll out the Mahara e-portfolio system across UCS. The URL is http://mahara.ucs.ac.uk/.
As this is a pilot project, we have implemented for students where they would use their UCS username and UCS default password. While UCS staff need to request an account via the link on the Mahara home page.
If you would like to discuss how you might use Mahara and e-portfolios in your teaching please email us at firstname.lastname@example.org
