Could someone create a script that constantly clicks the button on this page?: http://www.theanimalrescuesite.com/clickToGive/...

by clicking the button you help donate free food to animals!

setInterval(function() { window.location.refresh(); }, 1000);

That should do it, but it seems pretty weird to me.

I just joined, so I'm not sure how to run this script. I want to run it for a different page.

Tools -> Greasemonkey -> New User Script
There you can add a namespace, all URLs the script should run on, and the ones you don't want it to run.

Simply copy&paste my code, and everything will be done

Oy, I just found out that you the site only counts one click per person per day.

In that case you need to send them money.
