The user [BabuSudhakar][1] has so far only the changesets [7444772][2] and [7452141][3].
The reason for your additions not showing up on the map, for example [102654160][4], is that they have no [tags][5]. The renderer doesn't know if the thing you have entered is a house, a fence, a lake or a border etc.
You have to enter at least one tag that describe describes your object. Read more about it in the [Beginners Guide][6], specifically at section [Adding Details, and Tagging][7]. If the thing you have entered is a [building][8] the tags could look like:
- building = yes
- name = The Robotics Institute
After you have edited and saved your changes it may take from seconds to hours before the result is rendered and shows up on the map.
