Hello, I am about to launch a new website for children aged 7-11. It is about money management, finance and economics.
I need someone with

To review my website (you will be sent a beta version) and comment on:
#message: is it clear? Do you understand what this website is meant to do?
#appeal: is it colourful, fun and informative?
#would children like it? At the moment my pupils only use it but my hope is to grow its appeal to third party (kids from other schools)

THE IDEAL CANDIDATE (All these qualifications are non-negotiable. PLEASE, do not apply if you do not have them)
