Because of security issues PostIt is currently placed behind a vpn connection. Problems with uploading can be prevented by uploading from a Saxion-location or at home through an EduVPN connection. It is also possible to e-mail publications to Saxion Library (firstname.lastname@example.org), so that we may archive them at a later time.
Also, downloading Saxion publications from the HBO-Kennisbank is currently only possible from a Saxion-location or at home via a vpn connection.
We are working on a permanent solution.
