Register - register a new domain that does not exist.
Transfer - transfer an existing domain with an EPP-code. (this could potentially be dangerous if done too early)
Use existing - choose a primary domain to be set up for your account. This does not affect your current website but instead prepares the account with the chosen domain so you can start building the website and afterward point it to our servers.
Use subdomain - you choose a free subdomain for hemsida.eu as the main domain for the account. If you have not yet decided on a domain name or if you simply do not want to link an important domain as the main domain to your account then this is the choice we recommend. (The main domain cannot be changed later so this choice can create good flexibility and is therefore recommended by us.)
