Now that everyone has it won't be worth that much. Once enough people have it Google will change the algo. Thanks for the sript though.

It can be used to automatically fetch the PageRank of a given page from Google. In order to get the PageRank of any site you need to send Google the checksum value which is normally calculated in the innards of the Google toolbar.

Someone decompiled the toolbar DLL and turned the algorithm that calculates the checksum into a PHP script.

It tells you the google pagerank for any page you'd like. Only those who don't really understand pagerank will find it useful.

it guarantees you #1 position for every keyword you want.

the webmaster who runs it the most gets the highest ranking.

yes, exactly. once run your site will rank in the SERPs as soon as google updates them (usually under 30 minutes).

Please don't abuse it.
