Hello,

Welcome to OSM.

While we appreciate some details about building names or number of floors, your edit unfortunately contains several mistakes and it will take a lot of time to fix now.  It might be useful to read the documentation and observe mapping practices before attempting to edit the map and potentially destroy things.

1) Building shapes are imported from numerical imagery.  Please *never* redraw a building by following aerial imagery.  Such imagery is not accurate and will never show the correct shape of buildings.  If you do that, you damage the shape of a building.

2) Addresses are already on the map.  Please do not add fancy details such as postcodes.  If we do not repeat "1050 Ixelles - Elsene" on every building, it is not because we forgot to do that but merely because it’s not needed, given that we already have areas that say "all the points within this perimeter are in 1050, Ixelles/Elsene, Belgium…

3) In a bilingual territory, never remove a bilingual name to make it a monolingual name just because you prefer to see one language.  This is considered as vandalism.  Some people have been agressively doing that in the past and got banned from editing again.  No politics on OSM please.

4) Beware that what you change on the map may have very bad consequences.  You almost erased the VUB campus by mistake, while splitting a way.  I’ve just restored it.  Perhaps doing smaller edits for your first contributions will be better than attempting to deal with larger structures.

Have a nice day.
