thanks for highlighting these questions!
From my point of view, you are already moderating PMSE, and that's exactly how things should work - most seasoned members helping the community by keeping it organized and objective.
Besides, I believe you'll eventually have moderator grants. Our masters mr. Spina and CG (the one from the law) might be able to confirm this.
Edit: Oftentimes, I see questions I'd vote to close / delete myself, but happens that doing this would directly execute the voted option, which would go against the idea of having a self moderated community - and I noticed that unless it's a clear case of a question to be closed or deleted, other mods follow this approach too.
So, my view it's a matter of giving room to PMSE to naturally growth (to the point it'd be self managed only by users, not mods).
