Volunteer database?

[Watchoutbelow]

Does anybody know of any agency around where you can volunteer your skills to help in the case of large-scale natural disasters?
I believe there is a list were members of the medical and building profession can sign up, and should something happen, there is a large database for aid agency’s to draw from.
Is there anything similar in the aviation world?

http://www.redr.org/ is the nearest that I know of. There is also http://www.terresansfrontieres.ca/francais/projets/trans1.html, part of http://www.terresansfrontieres.ca/index.html but I'm not sure if they are actively looking for aviators. For those of a christian persuasion there's also http://www.maf.org/
