You do not need a membership to participate in this contest. I have selected an open area that all players can get to for each game, each party. We would never limit forum contests to members-only.
And any game/party will count toward earning the award. You do not
have to attend the POTCO party. Go to whichever party(s) you can. The goal is to just have fun and meet other forumers across all the sites.
