Licenses
Every submitted content must have a license. There are many available, so we have selected several of them which should suit most of you. There may be added more options in the future. The selected licenses "work" in the USA and may or may not be applicable elsewhere (although the wording is so basic that most parts should comply to local jurisdictions almost anywhere).
Creative Commons licenses
Attribution Non-commercial Share Alike (by-nc-sa)
This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms. Others can download and redistribute your work just like the by-nc-nd license, but they can also translate, make remixes, and produce new stories based on your work. All new work based on yours will carry the same license, so any derivatives will also be non-commercial in nature.
Attribution Non-commercial(by-nc)
This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.
