@Perturbative Well, if you want to contact one of the moderators in chat, then Daniel Fischer is probably the one who is most often in Math Mods' Office.
And Daniel Fischer was also the moderator who helped to get access for low rep users to logic chat room. (Although I was unable to find conversation which originally lead to this, only the part I linked.)
@Perturbative Re: One of the previous moderators on Math.StackExchange has informed me that users... Not that it matters too much, but I have never been a moderator.
