Are you sure you want to go to an external site to donate a monetary value?

I like this script as I find it very useful. I want to suggest you to make a grammatical correction: "Copied Successfully!" instead of "Copy Successfull!" in line 19. Also, the site "http://littlefinix.net" doesn't work now. Please fix these. Thanks.
I made the correction as per your suggestion, but as for the namespace: While I own the domain I don't plan on creating a landing page, the namespace is primarily there for preventing collisions.
