@sapwood, Greetings professor, the first 2 achievements were never validated for me and I gave up on it, I have read that at this time it is only validated to friends of friends who recommend the person in charge of validating said achievements, I think it should be fair that they do a Change of the person in charge, to generate confidence in the newcomers and it does not happen to them as it happened to me, since that demotivated me a lot ...
thanks
