Recently active questions in Threadless about design

Could you explain the revenue sharing arrangement between Threadless and submitting artists, and also if an art licensing agreement has ever been considered, instead of the current Threadless acquisition of all rights. In other words, to get the best quality of art and design submissions, it is common for a licensing arrangement to be reached (usually a flat fee, plus commission on sales). Threadless would attract higher quality artists and artwork by using a licensing agreement found commonly in licensing agencies. Thanks for your reply in advance.
