The dump will surely end up being stored at the The Internet Archive, but they are two different entities with different collaborators and different goals.

> Archive Team is a loose collective of rogue archivists, programmers, writers and loudmouths dedicated to saving our digital heritage.
If you want to contribute to the efforts, you can join #dprived (on hackint), once the Warrior (https://wiki.archiveteam.org/index.php/ArchiveTeam_Warrior) project is up and running, it's really easy to contribute. Basically run a VM and you're up and running.
