Laura and I want to make it as easy as possible for authors and adventure game designers just like you to write Sojourner Story Modules and to be able to profit from your creativity. That's why we decided to do what we call 'Grass-roots Licensing': offer a license to anyone who wants it under terms that would allow them to quickly see a profit from their work.
This benefits all of us: it allows you to sell adventures that you write for the game not only on our website but anywhere else -- including Amazon's KDP, iBooks, Kobo's self-publishing or on your own website. It allows Laura and I to keep our ownership of the Sojourner Tales intellectual property strong (by establishing a clear path for any authors to create commercial product). And it provides a clearly defined line between 'fan fiction' (written for fun and personal use) and licensed products.
'Grass-roots Licensing' is an exciting aspect of Sojourner Tales that allows you to be a part of its growth.
