This game requires its players to signup before gameplay begins. You didn't signup so you're not playing in this season.
Even if you had signed up, I would be telling you to reread the last paragraph of the post.
I'm hosting a Play-Along-Pocalypse that doesn't require players to signup and allows them to play along with the official STEEM-POCALYPSE while learning how to play it correctly and having fun. You're welcome to join us in the play along while you wait for the Season 7 signups to open.
