I've created a list for the Wikimedia Commons project:
http://mail.wikipedia.org/mailman/listinfo/commons-l
There are already 1.5 gigabytes of media in the archive after just two
months in existence. It is quite clear that this thing will become huge,
if we let it, and the task to organize this growing heap of media is
massive. I also think that the Commons could become a focal point of
creative activity by photographers, artists and other creators, but this
will require some rethinking to make it as easy as possible to participate
for people with no wiki foreknowledge. That's why I foresee the need for a
discussion list alongside the wiki as we have it with other projects.
The mailing list is multilingual. We'll try to use markers like [en] and
[de] in the subject lines and encourage people to translate messages into
other languages.
Regards,
Erik
