Sonic.net

I have been wanting the domain 'rushton.com' and when visiting said domain, it says it is registered to sonic.net. So I assume that it is available for purchase but I do not have a sonic account, therefore I cannot login to the domain tools in order to purchase the domain. I also have yet to find a way to create an account.

Any information at all would be greatly appreciated.

The page you are seeing when you navigate to 'rushton.com' means that the domain has already been registered by someone.
