Who actually owns the following domain names:
www.netchurch.com
www.netchurch.org
www.netchurch.net

Hello Pastortodd

To discover the owner of a domain name you need to do what is called a
"Whois" search on the internet.  There are several companies that
provide this service on the internet, the one that I use is
http://www.whois.sc

The company provides publicly available information on each domain
that you wish to find out about including name, address and contact
details of the registrant.  The registrant is the domain name owner. 
No private information is given out when this type of information is
supplied.

In the case of the netchurch.org this is owned by "R Earl" of "Harvest
Network" in North Carolina.  Full details can be accessed here:
http://www.whois.sc/netchurch.org

In the case of the other two domain names these are owned by a company
called "BuyDomains".  As their name suggests they are in the business
of buying and selling domain names, if you wish to purchase either of
these names you could do so from http://www.BuyDomains.com.  Full
details of these domains can be found here:
http://www.whois.sc/netchurch.net
http://www.whois.sc/netchurch.com

If you have any further questions on this subject please ask for
clarification and I will do all I can to help.
