Subdomain

Hello,

I own 8 domains all running one drupal page, but with different content. (languages :-) )
www.website.com
www.website.nl
www.website.co.uk
www.website.etc etc etc

I've just bought the domain
www.website.ro

This .ro domain goes automatically to my .com website. Because I still need to make the Romanian content.

I want to make the translations on a subdomain. So i want to make test.website.ro to translate before transferring it to www.website.ro.

Easy steps:
Ask hosting provider...

But he is on a holiday. How can I do this myself? I have no access to my FTP
