Hello,

Definitely, you can control content visibility very easily in DNN. For any given module, go to "Manage" then "Settings". Under the "Permissions" tab, you'll find the standard DNN permissions list. One of the security roles (by default) is "Registered Users". This role has everybody who is a registered (and logged on) user.

So, you can make two modules - the "public" one and the "private" one. Or, in your case, perhaps just a private one. In the private one, you make it visible only to registered users.

As a heads up, it's possible that this won't work well because the 'back' button in a browser usually pulls up the cached page in the browser's history. This often creates view state errors for web apps today. Still, give it a try and see what you think.

Hope this helps,

Mike
