Alright here goes.
When I try to go back to the homepage of this site I always receive the splash page with the age warning. Perhaps you could place a cookie that remembers if a user has already visited the website. That way you don't have to see the splash page every time you try to access the website's homepage.
The navigation looks odd for me, try the website in Firefox and you'll see that the last navigation item "contact us" is written over 2 lines.
I think the Letters to prison logo does not stand out enough from the rest of the page. Maybe you should make this larger. This might be just me but I think cutting off the ".com" and placing it on a new line looks a bit ugly.
The contrast between text and the background isn't big enough try to make all the text of your website as readable as possible.
