OH I see! I got the codes figured out then, thanks!
I know what happened that caused me to miss it then. I went to facespace.com, clicked the links to page 1, and then when I couldn't hit "back" anywhere (that I could find), I saw the url had "facespace.com/1" and I changed it to 2 and 3 to get to the other pages (as I figured that was the correct "solution"). Thus I never saw the NNN.com ad again. Maybe others did the same and missed it like I did. I'd suggest just putting that ad on all 3 pages and that should likely "fix" the "issue". But if I had dug a tad more, I would have found it. So player error more than anything.
Again, great job! Really polished overall and hope your future endeavors go well!
