Contributing to AskMonty.org
Our contribution terms are based on Wikipedia's.
For any text you hold the copyright to, by submitting it, you agree to license it under the Creative Commons Attribution/Share-Alike License 3.0 (Unported) and you are also required to license it under the GNU Free Documentation License (unversioned, with no invariant sections, front-cover texts, or back-cover texts). Re-users can choose the license(s) they wish to comply with. Please note that these licenses do allow commercial uses of your contributions, as long as such uses are compliant with the terms.
As an author, you agree to be attributed in any of the following fashions: a) through a hyperlink (where possible) or URL to the article or articles you contributed to, b) through a hyperlink (where possible) or URL to an alternative, stable online copy which is freely accessible, which conforms with the license, and which provides credit to the authors in a manner equivalent to the credit given on this website, or c) through a list of all authors. (Any list of authors may be filtered to exclude very small or irrelevant contributions.)
Importing Content
If you want to import content that you have found elsewhere or that you have co-authored with others, you can only do so if it is available under terms that are compatible with the CC-BY-SA license. You do not need to ensure or guarantee that the imported content is available under the GNU Free Documentation License. Furthermore, please note that you cannot import information which is available only under the GFDL. In other words, you may only import content that is (a) single-licensed under terms compatible with the CC-BY-SA license or (b) dual-licensed with the GFDL and another license with terms compatible with the CC-BY-SA license
If you import content under a compatible license which requires attribution, you must, in a reasonable fashion, credit the author(s). Where such credit is commonly given through page histories, it is sufficient to give attribution in the edit summary, which is recorded in the page history, when importing the content. Regardless of the license, the content you import may be rejected if the required attribution is deemed too intrusive.
Why the dual license?
After discussing this both internally and with others (most notably, Timo Jyrinki), we decided to dual-license the content here because it — at least in theory — increases compatibility with other projects. Some projects license their documentation using GFDL, and some use CC-BY-SA. By dual-licensing, the content here can be more widely used and reused.
We're also not alone in using this strategy. The Wikimedia Foundation (the parent of Wikipedia) also dual-licenses using GFDL + CC-BY-SA. Their reasons for doing this are explained here.
As stated by Timo: Think of GFDL + CC-BY-SA dual-licensing as the "One and Only copy-left license we never had".
