From the ReadMe.txt file:
form-length= the length the form field should be. Set to 0 for select, checkbox
or radio buttons, and set to '40x3' to make a 40 col by 3 row
textarea box. Set to -1 for hidden fields. Set -2 for admin only fields.
This is useful for the Userid field which will let an admin edit/view it,
but other users can't see it. All these fields only apply if you are
using auto_form_generation. You can alternatively, design your own form.
