Your Site Name

Where or how would one add their site name 'after' an installation? The hosting company failed to do that and I have searched language strings to no avail. Thank you for your help.

/inc/headerinc.php

$site['title']             = 'yoursitename';
$site['url']               = "http://yoursitename/pro/";

Thanks so very much, prolaznik!

Cheers!
