@mrGhL, From classroom schools, leisure and self-entertainment ... you graduate with an analysis that did not exist in the past and build on your idea ... and set rules for it that match your mood ... in the analysis. ..
There are many of these schools that I keep for myself, and they are not completely separate ,,, to set rules for them to be available to everyone and convince people to believe in them ,,,
I apologize for the long term..We use google translate
