I was thinking more along the lines of people being able to log on via Facebook into your site - less credentials for the user to manage can only be a good thing ...
Having never used your site before, I can't really comment but have you tried any sort of social media integration? Also, it would be nice for the site to be responsive and react to the size of the screen of the user - it currently renders the full site when accessed via a mobile.
What are the current issues with the gambling commission? Does your site offer anything to combat the issues?
