Reminder: Please Volunteer and Help Create a Unified Missing Persons Database
" We need community leaders that can help coordinate a massively parallel data entry effort so that thousands of volunteers can enter information from message boards across the web without too much duplication of effort. The thing we need to resolve first is how to coordinate such a significant effort."
This is something everyone everywhere can help with...you can give an hour--or more.
