our dear @delenn13 already linked the “cheat sheet”
https://206.81.1.216/t/badge-hunters-anonymous/10480/107?u=gnuffi
you can click on an individual badge even to read its info on how its obtained
bear in mind some can’t be obtained on chrono(email reply etc), +some are “time sensitive”(like user of the month) and others seem to be borked!
