anything is possible
you could remove the URL completely from the stats page, or create a plugin to display only the domain name.
make a plugin with the following filename: stats_build_page.php
PHP:
$TMPL['karls_url'] = parse_url($TMPL['url'], PHP_URL_HOST);
then in your stats template replace:
Code:
<a href="{$url}" onclick="out(this,'{$username}');" rel="nofollow">{$url}</a>
with
Code:
<a href="{$url}" onclick="out(this,'{$username}');" rel="nofollow">{$karls_url}</a>
and that should do it
untested code, so let me know if you have any troubles.
