Please note Pebble Pad is only used on certain programmes at the moment.
Our Pebblepad instance is currently set to be accessible via Myplace, through single sign-on only, which is why you've received the error if you've tried to access it by visiting the pebblepad.co.uk website.
You can access Pebblepad by first logging to Myplace (https://classes.myplace.strath.ac.uk/my/) and then going to the class for the programme or course in which you are a participant.
Within the course, there will be a link for Pebblepad + (green puzzle icon), which will sign you in to Pebblepad and activate your account.
