I'm kinda confused on whats really going on. I don't see WordForge doing anything wrong.
Yes you can download hacks, and install them on your board.
Yes you can give someone else on your board access to to download hacks.
Yes you can give someone else FTP access to add hacks.
Yes you can create your OWN template/and or hack and publish it
Yes you can buy someones site and take over it and run it the way you want.
Yes you can fire someone from your board, even if its the old owner or seconded old owner.
No you can't download someones hack, add it to your site and publish it as your own work, or publish it period.
Hope that clears things up some. Also, theres a few great features on vBulletin. Tachy user, ban user, IP ban user. So if you fire someone, and are afriad they might attempt to do harm to your new site. Change passwords. (board/ftp/cpanel, ect..) and use one of the three great features I happened to mention.
