A free text field in Ajax Register

Hello,
I would like to add a descriptive text to the registration, but not in form of a tooltip, but as a simple text on screen.
For example, an explanation under one of the fields.
As of now, I cannot see that option as all the others are form fields.
Any solution or a workaround?

Thank you

You could add a text field, set it not to be saved and disable it with CSS. Other than that no simple solution without code changes. I will add it to my TODO list to have a look on that.

Thank you very much
