either allow use of email from domain registration, or don't claim to
The domain registration page says "Verifying by email is the fastest way to confirm ownership of the domain. You can either verify using an email address on the domain registration record or by using one of several pre-defined addresses for the domain." However, in fact I cannot find any way to use the email address actually on my domain registration record (paleo.org), as it is not one of the four standard addresses listed.
Support query rather than an idea (and resolved now anyway).

thanks ... could not find where to send as support query.
