In any humanitarian crisis, an accurate contact list is critical to help ensure an effective response. Humanitarian ID provides a "self-managed" approach to contact lists. You, as a responder, can simply "check-in" to any crisis, provide your locally relevant contact details for the contact list, and find others responding. When you leave the crisis, you simply "check-out" thereby removing your details from the contact list (and email list). The process will be painless and will only take you a few seconds. But, the approach will save countless people the current frustration of trying to find the right contacts on outdated lists.
