Welcome to OSM and thank you for your contribution! 

None of the footprints you've added thus far represent buildings, so I've reverted your changesets.

Each footprint should represent a building. Please watch [this video about imagery interpretation](https://www.youtube.com/watch?v=CJ-vUwtS3A8). Sometimes buildings may appear to share a common wall, but this is sometimes an illusion; only map them with shared nodes if you have reason to believe that they really do touch.
