Pretty much, I think everyone has enough common sense and restraint to not leave people behind. Likewise, if someone hasn't posted for some time without any notice, they forfeit their turn. Actually, I will edit the OOC to have a section about posting, this way it might help clear up confusion.
That said, weekdays I only post late nights usually, weekends it is much more frequent. For now those that want to post more frequent with their partner can do so, maybe two or three exchanges. I will also be observing post rates and future pairings or groupings might be partly influenced by that so no one is waiting anxiously and no one is anxious that people are waiting anxiously for them xD
I will also define what major arc, mission arc, etc is more clearly on OOC in a bit.
For now, the orientation plot is the arc and the scenarios I provide right now are sort of like "small missions". Once these two get taken I might add more, but I am waiting to see where people go before I trigger them.
If I am confusing anyone, please don't hesitate to ask through message, for some reason I tend to explain better one-to-one in private.
