My texts are mostly additional remarks, additional skills and not the education itself.

My texts teacj skills but demand some basic starting level of skill and of civilized wisdom, which is at least school quality but widened by one's experience of life to new subjects too.
Since my texts are of many subjects, I think that inmany cases it would be clearer to refer to them by the subject and not by my name, since after all different subjects are handled somewhat differently and they are not all of the same quality and it is no use to read texts in some other subject ofmine if that does not support the subject in question.
