Michael Cox was an important person from the AMOS-list.
He was on the AMOS-list from the start and ran the list from may-1993 till 1998 (?), after which the AMOS-list was moved to oneline (which became egroups and then yahoogroups).
Besides running the list he kept in contact with Francois Lionet and extension developers. He informed people on the AMOS-list about updates, beta's and other AMOS related things.
