Dear Jaanharis, you are adding a lot of buildings and uploading them with a changeset comment of "home". 

1. You can add more than one building in a session, and then upload once you have created a handful. You do not have to upload every single building. As a changeset comment, please do not write "home", but instead explain what you did: "Added builidngs in NAME_OF_CITY" or so.

2. The editor can help you make buildings square with the "Q" key. Of course not every building is a rectangle in reality but some buildings that you have drawn could probably benefit from squaring.

3. Instead of using descriptive names ("rizwan shoe shop"), try to find the proper tag (if you type "shoe" in the feature box it will help you find the right tag for a shoe shop) and then only use "Rizwan" for the name, without "shoe shop" as this is already in the tag. This will also give you a nice icon on the map!
