As I have recently transferred my entire website over to WordPress, I decided to do the same with work's website - www.cgpartnership.com
It's basically the same layout as before, but everything is powered by WordPress, which means all the staff members can contribute to News items, update pages and add content.
The whole process has taken 3 days on/off in-between teaching, but I think it is suited quite well to the WordPress platform.
I've noticed recently that a lot of websites are moving over to WordPress as their CMS - even though it originally started as a pure blogging platform, many have found its simplicity to be ideal for end users.
I'll be working on V6.0 of slickhouse.com over the coming months, transferring old content over, but also editing the theme as much as possible. It looks like from here on I'll be using WP as the backend to many client web projects. Stay tuned!
