What is the policy on inactive mods?

I'm basically alone on 3d printing. It might be a good idea to recruit some help at some point, but I'm in a conundrum about what to do. I didn't create the community, and I'm the 4th mod down. The other 3 are not active. I don't want to discourage them, but I don't want the community to get discouraged by inactive mods either. I try to check posts at least a few times a day, and I have no intention of leaving. I kinda bounce around in interests and am neck deep in AI stuff at the moment. It would be nice to know I have some good help and am not alone here. Do I just keep kicking the can and hope the other mods come back?
