Thanks for the quick reply!
Here is the sign up link:

</form>
Here is what I have set for my ipn url under payment notification urls in s2member:
http://www.scrapvine.com/wp-content/plugins/wp-affiliate-platform/api/ipn_handler.php
If I look at the page source, my affiliate ID is there in the pagesource where the phpcode would be, and it was also there on the computer my hubby used when he signed up through paypal. Cleared my cookies, and it was blank, so I can only hope that means it is working?
I've read the documentation about using the http get or post, and was not sure if I should enable that in the options settings and place that code in the button also or if it should just work like this?
On a sidenote, will it matter if my site is linked to as http://scrapvine.com vs. http://WWW.scrapvine.com? I have it configured in wordpress currently without the www, but noticed I have www's in all of these fields.
I appreciate the help!
