I can't remember how many hits that site finally got, it was maybe 3000 uniques and only about 200 ever clicked on the FNP link to possibly join. For some reason I just couldn't sell a free pass. The AVS site in my sig is doing way better, and the membership costs $40/month. Go figure.
From what I could tell FNP's site list didn't send me much traffic at all when I first added the site; it was only after the site had been up for a few weeks that I noticed clicks coming from the search engine.
