I realise I'm probably being dense but hope someone'll be patient enough to help.
I've just bought my 3DC a Hudl2 from Tesco to share.
I've set their profiles, limited use to 1 hour a day for each...but then they never got asked to log in, and nothing's stopping them from just using it when and as often as they like!
How do you organise it so they have to log on as themselves in order to use the damned thing? I miss technology coming with proper instructions.
