Today I went to a site that displays information on domains. I wanted to look at how we are doing so I entered Morovia in the search box. Quickly surprisingly I received a message
Morovia is an Invalid Extension.
difficult to understand uuuh? Obviously you have to put your full domain name - in this case, morovia.com. Otherwise it thinks morovia is the top domain name. But even so, why it is called “extension”? File names have extensions; while domain names have suffixes.
