For a while no one has been able to join because of starting the group, now, you may become a Member and Submit and Suggest Favorites.
Also, Journals may be rare or not posted often because of being a little inactive and the co-founder has her own group. We may in the future bring in more co-founders and/or Admins. But for now you may only be a Member.
Lets hope the near future is bright and brings in more FNaF loving Deviants!
