We have a number of custom forms where we would like to display custom text the user cannot alter. We were able to do this on our very old in-house developed service desk application.
For example, on some forms we need to have a notice that the user is making a formal, legal declaration when they submit the form.
I am currently using a custom field as a text box but this is watseful of those boxes.
I suggest adding an extra set of "additional fields" for forms that allow text to be displayed that cannot be edited or deleted by the user and that does not consume one of the, already sparse, additional fields.
