The problem is that most people won't even click the "Register" link. For me personally it has nothing to do with email though. It's an obstacle which I can't be bothered with, even if it's just username and password.
The advantage of making you register is tracking your progress (and analytics, for the benefit of the webmaster). I suppose it could give you the option to just set a cookie, but that has the disadvantage of being device-specific. Also, some browser crashes can wipe out recently set cookies.

Hints please : Level 5
The questions need to accept more alternate phrasings.
I spent at least five minutes feeding alternate phrasings and spellings to 3 until it accepted one. They were all semantically/informationally equivalent. They would all have been accepted by, say, a fair pub quiz judge.
There are only 25 possible settings for a Caesarean cipher. You may be thinking of a substitution cipher, but the clue indicates a Caesarian cipher, as you correctly figured out. The problem is probably that you're feeding a correct answer in a phrasing that the system will not accept.
