First draft of the form has one role only. Then the next uses a tree to set up as many textareas as there are roles for the site.
Simple set up for a block that can appear anywhere in the block system.
Just the basics - get the Controller to work
There is now a form that takes in textarea input information based on role. It gets displayed in a block. The information is saved via State -- not yet using services (nor configuration).
Not available yet - but this will use a service.
