There have been two different Y.W. Moderator-25’s over time. The “Old 25” and the “New 25”.
You also missed Y.W. Editor.
Y.W. Moderator-42 is the oldest (in CR years not birth years) and longest continuously serving moderator other than Y.W. Editor. He is one of the original mods that started serving in 2008, if I recall correctly, when the Coffee Room was first established.
The ones that say Member instead of Moderator are former Moderators, no longer active as a mod.
