As far as I know I was and still am the youngest user in the CR.
I’m not sure where you would have assumed to have gotten this info but there are actually one or two posters who are younger that *we* know of. And I as a mod would not even claim to know that there aren’t others.
Regarding those who began younger, I think there MAY have been 3 or 4. But I couldn’t say for sure, and I assume you couldn’t really either.
Agav, someone left a pacifier in the coffeeroom last week, and a sippy cup, so it’s quite possible you have competition.
