I recently wrote a short introduction to the Lebesgue-Integral, following a path that was outlined in a German textbook on functional-analysis, but without any proofs there. The approach is probably a bit idiosyncratic but I think not without value.
Now I would like to invite potential readers to (proof)read the text, as I am not at an university and have no people among my friends or acquaintances who could take a look. Would that be allowed in the form of a question on math.stackexchange? If not, what could be an alternative to find some readers?
