Is there any sign of mappers being part of an organised activity or of someone having encouraged them to contribute?

Adding nodes to highways that cross but have no nodes, adding tags to untagged ways etc. I even try to make sure each village has one highway at least leading to it. However as I work west I'm coming across areas that have lots of buildings and lots of errors. I've zapped more than a few hundred duplicate buildings. I confess I have not put a comment on every changeset especially when the mapper has less than 30 edits. I'm seeing three buildings mapped on top of each other by the same mapper. One is untagged and its not just once. Interestingly some of the changesets are tagged "untangling the spaghetti" and I have sympathy with that mapper. In particular I'm seeing whole villages marked as a single building=yes, villages with highways that don't meet in the middle. Villages connected by tracks which doesn't match up with the African Highway wiki page. Most errors are mapped by mappers with not that much experience. The buildings in some ways are a nuisance as they both seem to be mapped from different imagery so often have been mapped crossing highways etc but the other problem is they fill the map so much so other features are difficult to spot like highways that don't quite meet. Are there any local Mali mappers around to chat with to see if we can get something organised? In particular we need the highway classification sorting out. The African highway wiki is fine as far as it goes but something connecting a village to a highway comes out as unclassified especially if there are square roofs in the village. In order to differentiate the highways that these connect to that connect a number of villages probably should be tertiary and the ones that connect towns and major villages probably something else. However I'd be much more comfortable with some local mappers making these calls. I'm not sure quite what to do. It needs a more organized approach. An Apple mapper has been in demoting highway=tertiary to unclassified and yes we did have a conversation however I'm fairly certain they are working remotely from imagery. Thoughts?
