Perhaps an eductional notice of "meet the moderaters" and an outline as to their duties as well as their limits and a notice of current availability of each (like if someones on vacation or otherwise away, maybe in each of their own words breifly how or why they have taken on the resposibility.) Some flag at the top perhaps of if and who is "on duty" at that moment. With all the concrete thinking that all of us may sometimes regress to it might be a helpfull instructive concrete way to "see" the human beings in any authority and associate them to their words rather than avatars- respecting of course privacy and discretion of said humans. When a moderater is drafted or retires it could be occasion for an update.
I know all this is availabe info in scattered places but sometimes its too much to look for and collect for oneself here and there.
