Hello,

I do not know what you want to do but I had a look at the various "maproulette" edits which you did in Brussels in the last hours.  It looks like a quest about schools but you did not add any school, you merely added extra buildings.

It looks like you are actually drawing buildings on top of the existing buildings.  I am afraid that is is not correct.  Almost all buildings in Brussels are already properly mapped.  Perhaps you wanted to map school polygons but mapped buildings instead.

I will inspect those edits but most of them should be entirely reverted.
