Forms with many fields
A long enquiry form is written in the office, not in the site
The signup for a newsletter is the site’s own and needs nothing else — an address or a number, a one-time code to prove it, and the consent kept against it. A form with a dozen questions is different. Those are written in KaryalayOne and the site shows the one that is there today, so a question added on Monday is on the site on Monday without anybody rebuilding a page. What somebody fills in goes straight to your office as it is sent; the site does not keep a second copy of it for you to reconcile later.
On its own, a site can take a signup. It cannot take a long form.
