I wish to buy the domain "tauonline.com".

It's registered by http://fieldlakeandsky.com, it seems. Field Lake and Sky appear to be an automated domain regging company or something, however they aren't replying to the e-mails I've been sending them regarding the domain.

Can anyone suggest how I'd go about trying to buy this domain from them, or would I have to wait until it drops to acquire it?
Thanks,

Have you been sending the emails to the registered email address for the domain as listed in the whois information?

You could always try contacting the registrar Name King and ask them to pass on your request to the account holder or registered owner of the domain.

Thanks for the info, I emailed the registrar a couple of days ago but as yet I've not got a response back.
