Recently re-worked the website I put together for LSA Ltd: www.travelf1.com to allow for easier updates by Lynden and the team.
It now uses Silverstripe 2.2.1 – an excellent open source Content Management System (we are using it extensively at work for “brochureware” – or sites that would otherwise be static HTML files – put together in Dreamweaver or similar).
Check it out if you are looking for a CMS – has some great features for both the end administrator (nice visual interface) and the developer (uses PHP5 and MVC).
