Register1 provides automated registration of the following domains:
.com .uk .co.uk .co .net .org .org.uk .info .biz .name .us .ca .cn .de .eu .me .me.uk .mobi .tel .tv .london .it .nl .es .ch .be
Manual registration required: .uk.com .eu.com .ie .gov.uk .sch.uk
Note that most European domains require extensive paperwork to ensure that there actually is a business in the country in question.
It is better to deal directly with a registrar based in that country. Our support department can point you in the right direction.
