I happen to be running a PHP-Nuke-based CMS on my clan's website. HOWEVER, this is not a nulled (because PHP-Nuke has been paid since 8.1) PHP-Nuke, it's a free fork known as Nuke Evolution Xtreme (found at http://www.evolution-xtreme.com.), forked when Nuke was still free. I want to know if this is legal.
