It's a new thing starting in 2011. I was PM'd about it from the site owner. Nothing will change for those with normal memberships. Those that opt to pay for a higher membership will receive different features like larger avatars, animations, a panic button, thank you options, etc.
Yeppers... just read the PM sent to me .. I opted to try it also.
Panic Button: The Panic Button will be placed at the bottom right of every post on the site. Club Members can set a URL in their userCP on the options page, for it to automatically forward to if the boss shows up unexpectedly. (ie: google.com)
Weird.........I set mine to advancedstatisticalmethodolgy.com, but it goes to crossdressingpoodleswrestlinginspaghettios.com. I'm screwed now.
