Licensing question on your choreography database. I cannot find any mention in the sequences or sequence submission form regarding allowed use of choreography published on this web site. I have been creating a new application for square dancing, and got a start with data that includes 37 modules from this database. Where an author is known, I gave credit in the module's notes. Do I need to remove these modules? Get permission from each author? What about sequences without an author given? Is everything here public domain, or copyright yet freely redistributable? I obviously wish to make use of these sequences to "seed" my system for beginners, but without stepping on any legal toes.
