I want to divert my domain name to another web address while I build the website. How do I do this?

So someone types in my web address and they're diverted to an alternative until I get someone to build the site for me?

1) Click on Domains (Websites / Web Tools / Domains ....)

2) Click on 'Set up domain redirection' (Under 'Transfer a domain')

3) Click on 'Redirect a domain'

Then just follow instructions....

Just in passing, if there has already been a re-direction made, then to modify, stop on (3) above and click on edit at right hand side of domain list.....
