While it's definitely a good idea to pull the theme across all pages, there are some flaws to your design. The menu/nav bar is hard to make out with the charcoal gray on black, you may want to think about the colors there. On the forum as well as on the blog rating side, both have very narrow content, look at the CSS for both and see whether you can go with a screen percentage that auto adjust to the screen size/resolution of the user. In other words, you can and should go wider, it would make both sites a lot easier to read.
Other than that, very nice work, details that others miss are there (favicon, etc). :tu::tu: 2/3
