It wouldn't have been hard, but would that have changed anything? Mods or not, it's up to you all whether you choose to keep playing. If the need arises, a new mod will be appointed, but right now, it feels pointless to designate a mod for a forum that's not getting any posts.
In fact, what keeps a forum alive is the community as a whole. In other words, its members. If members aren't posting, no mods will be able to change that.
