However, users should take care to heed the warning on this plugin’s directory page:
Warning! This is a very dangerous plugin to activate if you have untrusted users on your site. Any user could add Javascript code to steal the login cookies of any visitor who runs a blog on the same site. The rogue user can then inpersonate any of those users and wreak havoc.
If all you want is to display videos on your WordPress MU blogs, use the native Embed Support, Viper’s Video Quicktags or any of the other video plugins on WordPress.org. If you use this plugin your site will be hacked in one way or another if you allow anonymous users on the Internet to create blogs on your site. It’s very dangerous.
