Update 21/09/2016: This problem has been resolved.
Learning Online have contacted me to say our students and staff are still getting in touch directly with them as they are repeatedly being asked to register as a new user every time they go into access their personal BoB account. This issue has been identified and Information Services (IS) are working to resolve it.
You can still log into Box of Broadcasts but you might have to register again each time you log in. We apologise for the inconvenience and hope that IS will resolve this issue very soon.
