@pt2: I would never let my customers edit colors or font sizes. Allowing that might not seem much, but customers have a tendency to ruin your carefully crafted layout, content structure and seo strategy even when they can only change the text 
Blog entries ist a different thing imho.
@brechtryckaert: Talking of blogs, do you have plans to add a blog functionality to Charta at a later point? And what happens if I need to re upload the site. Will the changes made online disappear and get replaced by the content that’s in the bloc file?
