It seems to do what you want, you should create an app - then copy it and give editing rights to the copy.
That way people that have the original can use a form to add things. But not edit them.
Then you (or whoever) can edit (change the status)
I kinda have built it all into a DEMO app here.
One tab is supposed to be the user side.
The other is the ADMIN side.
But it really should be two apps.
