Dear Jillo,
Thanks for your feedback,
The problems with broken image on top 10 best casino section has been fix. On the top page, I have facebook icon using to login to me site using information from facebook, and facebook page link, google+, twitter put at the bottom.
On next time, I’ll try add news letter email block to my site, as your say. This is great idea, thanks a lot 
About time page load, I had checked Latest Performance Report for: http://opencasinobonus.com/ | GTmetrix is 1.30s, I think it ok
Still I welcome all feedback, thanks to all my friend
John
