Hi tom, thanks for your help. i'm almost done with customizing poll. i want to log votors ip address with $_SERVER['REMOTE_ADDR']. where should i put it in? there are just too many files there,,,,,,

The best place is the doVote() function in web/lib/client/CAjaxLikes.class.php. Put your code at the bottom of the function like:

private function doVote() {
	-------------------
	-------------------
	-------------------
	-------------------
	-------------------
	-------------------
	(put it here, the bottom of "doVote" function)
}
