You do not have a business website
That is fine. Register with the email address you actually use, describe your business in a few sentences, and add any public material you already have — an EPK, a catalog page, a social profile, an interview. A personal or shared email address is not treated as proof of an organization, so you will be asked to describe the business rather than have it assumed from the domain.
What you do: review the starting profile and correct it before you use it.
You already have a Whiia harness
Register with the same email address and choose the route for an existing harness instead of starting again. Updates keep your saved information, corrections and custom methods.
What you do: choose “I already have one” when the route is offered, then check that your context came through.
You are restoring a setup you saved
Restore from a copy you own — for example an approved harness repository you saved yourself — and reconnect the service accounts you use. The website does not hold a copy of your working context to restore from.
What you do: choose the restore route, then reconnect the services that task needs.
Documents, attachments and media are backed up separately from your harness files. Details are on the privacy and ownership page.
