Ask HN: How to set up a tracking on a wordpress membership site

I work with an LSAT prep startup, 7Sage (http://7sage.com)

We sell an online course. We use S2 Member to assign people to different categories based on which course they purchase.

We've been having trouble tracking conversions. I'm not technical myself. Something in the way S2 member handles javascript on conversion makes it difficult to pass data to analytics services such as Google Analytics or Kissmetrics.

Has anyone here set up a membership site using Wordpress and successfully integrated tracking? If so, which tools did you use?

If you don't know, where would I go to find out? Thanks.
