steven 12 (previously steven 11), who then became webmonkey.
in fact he might have been a mod when he was 11,
(the number at the end of his name was his age, hence he changes from steven11 to steven 12 when he turned 12).
admittedly he was only a mod of one section, not the whole forum like most mods are. but he was still the youngest mod that we've ever had.
