I noticed yesterday that i had 0 clicks on my adsense referral buttons, but i did have 1 signup, i guessed it just hadnt updated properly yet, but today it, beginning a new day, it still shows 0 clicks from yesterday, but 1 signup. Pretty cool, anyone knows how long the cookie timeout is ? It is atleast two days, as that's how long since i had clicks, could be much longer ofcourse. That i havent made any revenue on the referral links yet in the months i have had them up is another matter.
