They might be on vacation, they might be extremely busy with the current age coming to an end as Scar hinted at, they might be having internet problems, they might be extremely busy with work, they might be dealing with a death of family/friend, I hope they aren't but they might be gone and waiting to autodelete.
I would try to find out who the most active imm is and see if I could write a role to fit their religion. I wish there were enough imms that would allow people to write roles and pick the religion that fits them best, but those days are gone unfortunately.
