Requirements to post in the gameroom

[Sevis]

G'day,

It seems like the Gameroom requires something more to start posting than the otther boards in the "Miscellaneous" group (except the Backroom, of course). Is this board invitation-only, or is the minimal post count required higher (and, in that case, how high is it)? I would like to join the upcoming "That Creeping Darkness" Mafia Game, but cannot post.

Thank you,
Sevis

EDIT: Thank you, Beefy, Sigurd :D
