Title is hopefully self-explanatory. During the early growth, there were a number of examples of users setting up magazines based on popular Reddit subs but then losing their initial enthusiasm for kbin.

I'm an active user of one such sub, which has taken off in the last few weeks after a slow start, but where the only mod hasn't been seen in over a month. How do we either replace them or get additional mods added, when there's no way to get in contact with them in the first place?
