We should create a Public Group on Flickr. Everybody interested in submitting photos related to Ottmar Liebert + Luna Negra would sign up for a free Flickr account and upload photos from their computer, or directly from their cellphone. There are two types of Public Groups on Flickr. Both groups allow anybody (meaning members as well as non-members) to view the Group’s photos, but while one of them allows anybody to submit photos, the other is by invitation only. I think the latter is the better way to go, because it will take less administrative work.
