I have implemented CouchCMS into an existing website, http://www.exit5.be/ as a test. In less than 2 days I have implemented it and partly mastered CouchCMS.
The easiness is amazing.

Hello and welcome, Koen

I am glad you liked Couch.
Less than two days is pretty impressive considering that you built a multi-lingual site.
Good job

Thanks

The site already existed so I didn't had to spent time on that.
And like I said, I only mastered Couch partly. Haven't tried clonable pages yet.
