I'm curious how others are making changes to pages that are live.  I've seen modules by Engage that allow changes to text modules to be approved before they go live and there is the handy import/export in many of the text based modules of DNN. 

My current setup is to have a dummy page that only people in the Editors group can see.  If they want to change the announcements on our Home page I will export the announcements content and import it into an announcements module on the dummy page.  The user has edit permissions here so they will add the new announcement and when they are done the appropriate people will review it and approve.  Once approved it's back in my hands and I export the data from the dummy page and import it back on the home page.  Of course I will be adding a few more people to the moving between pages process so I'm not a bottle neck, but that's the general idea.

I'm running into a bit of a roadblock when it comes to redesigning a page (adding new modules, moving existing ones to new locations on the page, etc.)  I can't find a good way to do this on a Live page without the users being able to see the work in progress.  I could set the page to be only visible by our editors and they can go to town, get it approved, then change it back.  But that means the page is hidden from normal users until it's approved and that could take a few days.

How are you all handling this?  How do you make changes to a Live page and not have users see the inbetween steps of getting the page changed?  How do you handle updating the content of modules that are already on the page that need to be approved first?
