I know this has probably been covered many times but here is exactly the script I am looking for: I need to have a script where people will get points from logging into my forums.They would also get points when they refer a friend and that friend signs up with the link they send them,also they would get points from each referral there there referral had join.And last but not least from completing sponsor offers and surveys. I hope that did not sound crazy 
Most likely there is going to be a mod for the forum script you are running, so the first thing we would need to know is the forum script you have running.
I am using Simple Machine Forums
