123domain.eu was the first German registrar (besides two registrars from Estonia) to be accredited as an "Elite Partner" by "Eesti Internet SA" at the end of July.
These guarantee the customer and domain owner an alignment to the "Best Practices for Registrars" - guidelines, which belong to the standard and daily business at 123domain.eu anyway.
By the way: for some time .ee domains can be registered without a local Admin-C and thus without a trustee service. Check your domain portfolio for an extension to Estonia!
