Yes! 😊
I have been following ACS (and OpenACS now) for quite a while and several month ago when we started the project I decided to go with ACS. The initial idea was to go with Zope, but that has changed now. I don't want to start again with the endless discussion. We are using Zope for other projects and it's a very good tool, but for many reasons it was not what we needed to power our websites.
It's going to be more than just Greenpeace's website in english, we aim at making it truly multilingual (support for european languages, japanese, thai and many other languages, well, places where we are present). And all the code will be released under the GPL.
