The login is better if you place it at the lower bar.The borders are better in black instead of that light blueish color.
Red: Move the quick login to the bottom bar. Green: Your main content boxes don't have any side borders yet... Orange: The borders would look better black, not cyan. Easier to see. Pink: Bold for tites? Once again, easier to see. Cyan: Move the online stats into the corner. At the moment it looks like you wanted it in the corner, but couldn't make it go there. Looks good, though. Just a couple of possible improvements.
