Hi;

I can use a little education on this topic... what is this domain?

 

http://www.calcium.com.biz
|.busycorp.net/?&rev=dcc2&aff=ami&id=ami08

 

To test it I tried Calcium.com but that domain is for sale, then I tried calcium.com.biz and it worked.

 

A double extension?

 

How does that work?

 

Regards,

Kami
