Our office produces a newsletter where several people contribute articles. Each person is in charge of 1-2 pages. Each page is set with a template consisting of two columns and a couple pre-filled textboxes.

However, when people are creating the text based on this template, all they have to do is hit the delete key in the wrong place, or otherwise add enough text to "break" the template and all the preformatting moves.

Is there a simple way to lock the template so they can fill the premade textboxes and columns without changing the shape and location of them?

Thanks in advance.
