For many years, the German DARC managed this database.
Then they passed it on to the RSGB.
The OM handling it for the RSGB has this e-mail address, but e-mail is bouncing. And the RSGB doesn't know anything about ITHE. firstname.lastname@example.org.
Is this unique database dead? Folks traveling the world might know.
