I have couple of comments that i hope you find them useful
1) Banner: I suggest degrading of color of the banner to match color of the holder place which is gray and banner is so white (Not Even Good With Photoshop)
2) The Clutter of (FAQ, Register, etc...). They are all above each other which is not justified.
3) Register now: The image is not bad but the space between register and now is too big. The image also could be imrpoved.
4) Login textboxes are on the buttom of the site, which means that the user have to scroll 4 inches each time he try to login from main page
5) The recent posts: I don't believe anyone will go that deep to look @ the recent posts. If you really want someone to see it, then you should put it on the top.
6) Affiliates: The site is too tall and no one will scroll that much to click on your affiliates links thus, you won't be giving any traffic back to your affiliates which risks your site rank
I hope that you find my review useful. Have a nice day.
