Hi, ok, that's great news new people are trained to build the map. Its important to explain them well how relations works since many people have work hard to get the map of Cameroon so detailed. There seems to be a miss-conception about residential area as you can see in this relation:
https://www.openstreetmap.org/relation/10976082/history
This is mostly forest with some farmlands and not a large residential area like a city. There are several large other patchs like this that have been erroneously classified as residential in the Center region. Please can you check this as well.
