I asked a supermod to remove me as mod from the Unreal-series but it only removed me from the series itself not the individual games. I want to be removed from all of them.

You can unmod yourself. Go into the edit game page, go down to moderators, and press the trash bin beside your name.

Edit: Ignore me, this only works for super mods

^ No he can't, Moderators do not have control of the moderator panel, only Super Mods do.

Forgot about that, my bad. Mods should probably be allowed to unmod themselves.
