ADDDITIONALY ...
Your Page Text is extended too far across the page and interfering with the other elements: it is important to "emphasize" Content by creating obvious distinction from the rest of the page, so you would be better off "narrowing" your Page Text display area significantly (not your white "Page Area" shape, but the Text Displayed on that Page Area).
Open your Test Page in another browser Tab, and then open the Demo in a Tab next to it so you can switch back and forth to compare the differences and to prove to yourself how the eye will pick up on the "problems" of the page before it begins to actually "read" the page. This is how carefully you must create a balanced visual appeal and invisibly integrate the technical aspects. I would also check your image top-right of the Page .... the shadowing is much too dark and dis-similar to the left-margin Navigation area which has purposely been given a Shadow effect to make it stand out from the Textual Page Content: giving other elements on the page Shadows tends to appear overbearing when not fitting with the obvious continuity, especially when those elements are "additional visual contributions" and not formally linked to Page Optimization. My point is that it is not necessary, and genuinely is a distraction: "Less is More" To "match" the radiused shape of Left navigation gutter and the AdSense border (to maintain visual continuity) as seen in the Demo (which has a more balanced and cleaner overall appeal), simply create a SHAPE and select Radius Corner, and then select "Fill With Image" and your selected image will automatically be re-formatted with matching radius corners.
The explanations above may be over-the-top and technical, but simple visual appeal should always be your initial guide to a balanced, technically-compliant Visitor Appeal. Every detail is important and contributes to an optimally performing and functionally complete website. I have taken the time to comprehensively outline throughout this thread many of the methods, logic, and techniques that are not fully detailed elsewhere so that the many others reviewing this might benefit from the sharing and discussions. I would still move your Page Text at least another 5 pixels to the right - as it is now, it is too close to your navigation for visual comfort. You can always add additional items under your Navigation area to 'balance' things out once you know what all you'll be presenting as Navigation. I would also move your White Page Shape Area (and everything else on the Page) DOWN at least 3-5 pixels in order to accommodate your yet to be installed MenuBar Navigation, so it is not unduly affected by the bottom shadow of the header. You should eliminate the Hyperlink on the Text on the upper-right image and create over the entire image a transparent SHAPE to hyperlink to your Forum instead. This allows you to utilize the entire image area as a link rather than simply Text or image area around text placed over an image (you should see this inability to not be able to link both elements at the same time, just as in your Header: you should also create a transparent Shape and Hyperlink it rather than have your header linked only where text is not). You have formatted the text in this image very unusually, and it is not appealing with the white highlights: use the LogoMaker instead to achieve better formatting and shadowing of non-bold text with colors that match your Header (for continuity).
