I tried that link last night and it went bersrk, opening dozens of new windows.. panic stations, and when I re-opened it the same thing happened so I gave up and went to bed!
I believe Guy has broken his arm and wrist, and was knocked out. They'd have easily known that because he stopped talking! However, it looks as if he's been relatively lucky.
My grandson Jake will be devastated. Guy's biggest fan. Thought I'd wait until he comes home from school to tell him, or he'd have done no work today!
