I remember some time between 2011 and 2014? /g/, /sci/, and nerds from a couple other boards were collaborating on some cicada-esque challenge quiz, trying to beat a team from Reddit. We coordinated on an IRC channel called #300kstarting (p sure it was started by a /sci/fag lol) on I think Rizon? Does anyone remember what that was?

Sounds tight anon but we're old on here now I'm afraid.

Sounds like they had fun.
