What the builder does not do, so you can plan around it
There is no drag-and-drop layer, no rack of templates to shuffle between, no field for pasting code and no custom domain. The page lives at its own address on our domain and that is the whole arrangement. You cannot run two dates on one page, so a repeat session is a second build with its own link. Nor does anything publish itself: an unpublished page stays invisible to guests, which is why half-filled tabs never reach anyone by accident.
What it does keep is the record. Once the page is live, the same answers drive the attendee list and its statuses, the count of page views against registrations, and the timed emails before the start. That is the case for building from answers instead of from a layout: the invitation and the administration come out of one pass, and you do not reconcile them later in a spreadsheet.
