Hi Heiko, Some sites that are pretty prominent are www.breastcancercare.org.uk and www.findus.se. There's also the client list on the Zope site - http://www.zope.com/ZopeClientList that has more. They're not flash things-whizzing-round-the-screen sites though, if that's what you're after.
Mail me off list if you want anything more specific. Miles Waller [] j a m k i t www.jamkit.com -- http://cms-list.org/ trim your replies for good karma.
