I have iMacro extension for firefox, which is awesome, I use it to do repetitive things on websites, like clicking links etc. However my computer needs to be turned on to do these things. I have a server which runs PHP scripts, and it is always turned on. Does anyone know a PHP script i can use, for example to visit certain links. Or to click certain buttons on websites, and then repeat those actions say once every hour. Help would be very appreciated thanks.
