I haven't lived in London for well over a decade and lots has changed so I may be asking a LOT of stupid questions, sorry. 
First question, I'm trying to apply for a Zip 16+ Oyster photo card. I'm on the TfL page for it and the first thing is to use the "create an Oyster photo card account". I have to do it because DD is under 18. So I clicked the button but when I fill in the form it says that DD has to be over 18 to have a photo card account, so I think I've been directed to the wrong form. Am I going to end up having to do it in person?
