For increased security, we have now switched the VLE over to use HTTPS which uses an encrypted connection to communicate between you and the VLE. You shouldn't notice anything different on the site itself, but you may need to re-enter your login details the first time you use the new site.
You will probably notice a padlock icon next to the site name in your browser bar. This indicates that communication to the site is protected using https. Most browsers allow you to click on the padlock icon to confirm that the site is secure and allows you to view the certificate.
If anyone does spot anything which doesn't quite work as expected, do please let me know.
