I just created a "Log in" thing for my website so users can (as the name implies), log in. I used this tutorial:

http://www.youtube.com/watch?v=4oSCuEtxRK8

and part 2 and part 3 for it. I did everything correctly as I have tested it out by using http://localhost/index.php and everything was fine. So my question is, how do I put it up on my website for public people to access it?

(My website is a http://www.sites.google.com site -- meaning it's a website powered by google)

Thanks in advance!
