I wonder...
Do we stay with the posting order or can we post as we see fit....
or is this thread dead?
My rule of thumb for posting order has always been to keep the order unless your character is in direct interaction with another, keeping a dialog for example.
So in this case, I would say go ahead and reply. The others will post when there is an opening or when they feel comfortable.
I surely hope this thread is not dead and I'm sorry if I delayed it for too long.
