If you have any questions about how to use the Churcher's College IT (such as computer rooms, laptops, Firefly, BYOD WiFi etc) then it is probably explained here. If it is not already covered on Firefly or something is broken, you can tell the IT technicians using this website http://support.churcherscollege.com (if it doesn't work, you can email support@churcherscollege.com). This would also include if you spot any damage to IT equipment in college.
If it is urgent, you can also go to see the IT technicians in their office on the side of the sports hall (you will need permission from your teacher to leave a lesson however).
