Braindash - Website I've been working on - Feedback Needed

Hi everyone,

Have been working on getting this website up and running for the last year or so and would like to know what you all think. Its a skills gaming website, with braingames and quizzes which you can play for with money.

Anyway the link is

http://www.braindash.com

Let me know any feedback, whether or not you like the site etc.

Thanks

Sam
