The Humanitarian OpenStreetMap Team now has a mailing list.
During crisis, the HOT list supports coordination among the OSM community, along side appropriate local country lists, and the talk/dev lists when needed. It is the point where disaster responders and affected people can connect directly to members of the OSM community ready to help. In quieter times, the list helps HOT to prepare resources and improve its response.
Note that talk/dev are still good for mobilizing the wide community to a HOT activation, but details of the response can for the most part safely move into this list once we get critical mass of subscribers.
Please join if you are interested in helping HOT, or need HOT services. Thanks!
