All future works too? That's a terrible agreement on the part of the artist.
It is at the artist's discretion to license with DoujinPress on a work by work basis as spelled out in our agreement with Blue Muffin, and DoujinPress is bound to protect our mutual interests for all works submitted to DoujinPress. At this time Blue Muffin has indicated she wishes to license all past and current works, as well as her next upcoming work with DoujinPress.
DoujinPress does not rope artists into bad agreements. Should Blue Muffin choose to not submit a future work to DoujinPress, it will not be licensed.
