Thanks for the quick answer.
Pardon my insisting. Maybe I am temporarily dumb, but I don't get your explanation.
Where is the "Go" button for Co-creator that you mention?
When I go into the page of a model, and set "Edit page" to "ON", I see a link "Edit this Co-Creator" (or "Make this model a Co-Creator") in the lower left corner. I guess that's what you call the "Go" ?
When I click that, I get a pop-up where I can enter the co-creator information. That has a button "Save Template Details", but nothing that says "Publish"?
And, as I asked before, is there a way to reset this "Co-creator" status of a model? I don't want this.
Greetings
