Cool idea. Site looks great too. One small thing: there is a typo: "REISSUED GIVES YOU EXCLUSIVE ACCESS INTO A WORLD NO ELSE CAN DELIVER" should be "REISSUED GIVES YOU EXCLUSIVE ACCESS INTO A WORLD NO ONE ELSE CAN DELIVER"
It's still very alpha and needs some cleanup, I made it quickly for a site that needed the feature and figured it might be useful for someone else. Let me know what you guys think.
I will merge any pull requests on github if you have any bugfixes or enhancements!
#edit Also, i've been a long time lurker on HN and finally decided to register and share! Thanks for this awesome community.
