Trevor is doing a great job on the site, but it does still need some tweaking.
You can see how the teaparty07 site looks at three common resolutions here:

It looks good at high resolution, but is not great at 800x600 or 1024x768. At least 10% of viewers still use 800x600 and over half use 1024x768.
This is just a suggestion - can you make the top of page, including the text, a single image and then use percentage layout for the image?
Here is an example:

Resize your browser horizontally to see the effect.
