You are about to upload your work under a "high-free" licence.
You will be given a choice of licences at the bottom of this form. The following is an overview of the available licences.

Creative Commons Attribution
This licence lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation.
This is the most accommodating licence in terms of what others can do with your works.

Creative Commons Attribution ShareAlike
This licence lets others remix, tweak, and build upon your work, even commercially, as long as they credit you and licence their new creations under the identical terms.
This licence is often compared to open source software licences. All new works based on yours will carry the same licence, so any derivatives will also allow commercial use.
This is the licence used for text on the Citizendium.

GNU Free Documentation License
The GFDL is designed for software documentation and lets others remix, tweak, and build upon your work, even commercially, as long as they credit you, licence their new creations under the identical terms, and attach a full copy of the GFDL Legal Code to the work.
Having to attach the full legal code can mean many people will find it simply impractical to use your work in a print publication, but this is not a problem for electronic projects.
This is the most restrictive licence on this page.

Dual-Licenced (CC-by-sa + GFDL)
This gives people who may want to reuse your Work the option of using it under the terms of either licence. Dual-licencing in this way avoids the problem of using a GFDL image in print publications mentioned above, because people can choose to use it under the CC-by-sa, and it also allows those people whose projects are GFDL to choose to use it under the GFDL.
