As you can see, we are using a .co.nr domain name on our forum.
And wherever you go,. the url remains the same (www.wildfire.co.nr)..
The reason is because the domain name .co.nr is a fixed domain. Cannot be changed.
But it's just a sub domain. Proxy inshort. For shorter name purpose.
You can use http://www.wildfire.5forum.net to get the specific link you are looking for.
