I need to implement 4 things into my PHPProbid auction site.
I want an affiliate script...that allows members to upgrade from one level of a store to another level and eventually they should have a free store after they refer X amount of people.
I also want to implement a system where users have to buy bids to keep spammers away from the site.
I need my signup process connected with my get response autoresponder so that when people signup they are connected to that newsletter and not the newsletter of the script
and I want a refer a friend during signup where people can invite their addressbook from popular email providers.
