To get you thinking about good changesets lest look at WAY: 103138423. Previously it was tagged as a building; you changed it to a roof. Why? Did you see something in the imagery to confirm it? Have you actually seen it yourself? If it was previously mapped as a building, then it's possible that a future contributor will map it as such again. If they look at the history and find a good explanation for why it has been mapped that way then they'll be less likely to change it. If they do change it (and it is in fact a roof) then it'll be easier to rectify and maintain. Please keep this feedback in mind when contributing in future.
