I'm struggling on how to build/rebuild these new tables.
I've currently got five categories that users subscribe to:
CENTRAL
WEST
EAST
(etc.)
I want those categories to be standard with sub-categories that users subscribe to:
CENTRAL
Item1
Item2
Item3
WEST
Item1
Item2
Item3
EAST
Item1
Item2
Item3
(etc.)
I will manually propagate current subscribers into all sub-categories accordingly once I'm done with rebuilding tables, but I'm stuck on how to create the new tables and relate them for the web.
