Keep your website. ECO is the private side behind it.
Only what the office approves ever appears outside.
The office writes a short item: a word of the week, an upcoming event, or a story, in text.
Nothing goes out until the office approves it, for the dates it chooses. Any change takes it back off the website until it is approved again.
The Tribe’s webmaster pastes one small piece of code once. From then on, approved items appear on the existing website in the website’s own look.
An optional feature, switched on when your office asks for it.
