I did think of that, but I was afraid we wouldn't sign the keys properly. I
have used Gnome Seahorse and its so confusing.

Thanks for the link. Never found this in my Google search results.

Thanks for confirming this is possible. Do you have a link in what you need
to do to link your keys to a signing policy?

That's what I was thinking of too?

If the "new user" is known to you, could you "trust" their key to grow the
web of trust?
