It is poor that a lot of folk still use the term 'non-league' to describe any status below League Two.
It is rather like folk telling the old Skoda jokes. Volkswagen began buying Skoda shares in the early 1990s. By 2000 Skoda
was fully owned by Volkswagen and radical changes were made. A Skoda is a Volkswagen. Indeed since the early 2000s the prestige vehicles that you see in the Tour De France 'Caravan' (preceeding procession) are Skodas.

For ease of understanding world wide our football divisions from the top downwards should be called :-
Division 1
Division 2
Division 3
Division 4
Division 5
Division 6 North & Division 6 South

We should not use the disparaging term 'non-league' to describe that which is below Division 4. Division 5 is merely 1 step down
from Division 4 just as Division 4 is 1 step down from Division 3.
