I think that for a current ambassador to move to a Community Lead, it would be ideal that he identifies a potential Ambassador to replace him since if @Cristinh0 becomes Community lead, there should be someone replacing him as Portugal Ambassador. The Portugese community lead can then oversee and guide the Portugal Ambassador, can also work on Identifying and training other NULSTARS and other Ambassadors in other Portugese speaking countries like Brazil etc etc.
Eventually, I could myself do the same for Africa, because Africa is so Big with 54 countries and at least 140 languages. Of course, it is still early for me, I am still at the stage of starting a NULSTAR, but @Cristinh0 is leading the way
If budget permits, I even suggest that there should be One Community lead in each major region eventually. Now that chainfactory is operational , it is time for a BIG Marketing push for Adoption
