Hello #user_5359,

She is a member of a 10 persons' OSM team who are adding the remote rural community risk and disaster data what will be later used for an interactive portal for future decision making. Many thanks that you have pointed all the tag erros thay are doing! Its really alarming for our som dataset. I gonna guide them to make all the corrections.
Thanks for your comments and support.
