Nice to meet you, and welcome to CAP! We are excited to have you here and are looking forward to seeing you around.
The layout looks great and is very viewer-friendly, I would just work on adding some good unique content and finishing the Casinogames section (like you said you are going to 
). Great that you are already thinking ahead to gathering e-mails, I would just make sure that the subscribe button is displaying the way that you would like it to as well.
Of course, you will want to start posting and making your social media outlets as active as possible. I would start doing this ASAP to make sure you have some good stuff up when you start to get some good traffic. Also, I noticed that you also have Vegas Palms listed as top rated, but they have the least amount of stars of all of the casinos listed.
Great job so far–looking forward to seeing how the site grows!
