Photoaid started as a grassroot project to help raise funds for the South Asia Tsunami victims (via the Salvation Army)
after the project ended, the threads titled 'Photoaid' became the platform meant for members and friends who participated in the project to keep in close contact with each other. of course it's not exclusively meant for those who participated in the project, other members are welcomed to join the community.
and we hope there won't be a need to 'activate' Photoaid again for any calamity in the region.
