I also develop and design some themes for PostNuke. Below is the list of the themes I made which are available to public.
An AutoTheme (AT) theme I made which is available for public download. As the name already said, this theme is really a minimalist. Without any images at all, just text only. It uses CSS quite extensive, although not tableless yet. Click here for preview. This theme is working with AutoTheme Lite (ATL) .7. Please download the ATL .7 first on http://spidean.mckenzies.net before using this theme. To use: unzip the package and upload all.
- Yet Another Minimalist
Just like Minimalist, this theme is working with AutoTheme Lite .7. This theme is less minimalist than the first one. It uses some images and the rest are CSS-dependent. Click here for preview. You may freely modify this theme to display your preferences. To use: unzip the package and upload all files to your PN themes directory.
