A : Within the notice creating pages you MUST use the arrows on the bottom of the pages to go back or forwards. If you have used the browser arrow, keep in mind that it is often possible to recuperate the page by pressing on "refresh" (icon with two swirling arrows) and then on "retry" when the popup comes up.

A : In the course of creating the notice you may change templates at any time. Once you have chosen a new template you just have to save it. It can then be visualized for approval.

My advice : use the "visualize" facility frequently during the creation of the notice to check the progress and general appearance.
