Hi,
What is NESTED usefulness?
I want to organise my groups. I have a website of 80 categories organised in 4 levels, and millions of cities in a table order by Country/Region/Subregion/city.
If user James is in group country-category-A and group city-category-A NOT NESTED.
What is the advantage to add James in 2 nested group If he is in group country-category-A and group city-category-A NESTED?
Will James have more options, more notifications, why it should be useful to have 2 Group nested instead of 2 Groups in 2 categories?
In fact, I simply need to know how is the best organisation of my categories and places by Groups, categories, nested?
Regards
Gauthier
