Do I have to wait for DreamHost to make the .uk domain available? Because right now I don’t see any other options to register my .co.uk rights.
No need to wait! We do support the registration and transfer of .co.uk domains, as well as .org.uk and .me.uk.
What we don’t support yet is top-level .uk domains (like “welcometothe.uk”). That’s because those just became available to the public today; we will most likely provide support for them as well as soon as they’re available through our domain registration provider.
