This is just something I've been curious about for a while, and today, my curiosity peaked. We have around 32,000 members here, so you'd expect, on average, nearly a hundred member birthdays everyday. Yet, I've noticed no more than two or three birthdays listed on most days. I'd imagined that only the members that were new or active would make the list, but today's birthday member registered in 2004, and has 0 total posts. https://www.physicsforums.com/member.php?u=16931 What's the deal with this ?
