Unless I missed something, I cannot see how are edits controlled with Medium Content Editor. It looks like any user can simply update an editable area.

Is there an Admin login? there does not appear to be a way to save the updates in your samples.

Hello Robin,
It is up to you to build an admin panel and setup users/permissions using DMXzone App Connect, Server Connect and the rest of our database tools: Database Connector, Database Updater, Security Provider.

Medium editor integrates with them.

Using the Security Provider you can hide the Make Editable check box and only show it if the user is logged in.
