I have no objections to a fifth player and will ultimately accept whatever the GM accepts.
With that in mind, I will raise two potential issues:
1) I really like the NAN theme of our PCs and would like to preserve that, if at all possible. Everyone being In Debt is also an interesting nuance.
2) To Jack's point, Stoneglobe dropped Umbrae Europae less than two months into the game, with no notice. Stoneglobe also dropped Tri Tri Again with no notice. Same with Sorting Spaghetti. As a PbP GM, these are all cardinal sins to me.
Stoneglobe, this is also your first post in two months, and you haven't done any significant posting since 2016. I guess at this point I'd be interested in a compelling reason why we would should wait for a player who has proved themselves to be so unreliable. If we move forward with this, I would suggest that we all commit to a Code of Conduct to establish expectations around player participation.
