I didn't say that you made a bad work,I had only say that famrs can be find in evey country.The problem is the number and the use you do.
As you have just said,also your country has his farms,few but farms.
I think that you are one of the best coach in the world in involving the community,because czech users really follow your indication to improve your national team.But you can't know what every team will do,What I mean with the term"sensitize the community" is that if someone is going to leave,other users could contact you saying"Hello coach,this X manager is leaving the game,maybe you can convince him to become a farm" so you can use that team as a farm
It's more a community duty than a your duty... ;D
In Italy we have problem to find so many farms as the number of great players we have,because probably the managers that leave the game are the managers that are less involved by the game and community,so it's difficult to find teams with the right characteristics to be farms,but definitively it can be done...
Surely,farms are needed only for few players,because the work has to be done also in the field where you are a great expert,creating competitive players with the less possible salary
