copyleft.org ============ copyleft.org is a collaborative project to create and disseminate useful information, tutorial material, and new policy ideas regarding all forms of copyleft licensing. ### The Copyleft Guide and Tutorial The primary project currently on this site is a tutorial book entitled [*Copyleft and the GNU General Public License: A Comprehensive Guide and Tutorial*](/guide/). This guide describes the policy motivations for copyleft, presents a detailed analysis of the text of various copyleft licenses, and gives examples and case studies of copyleft compliance situations. ### Getting Involved There are various ways to get involved with this project. The primary copyleft.org website is a wiki, and we welcome helpful edits and additions. For the aforementioned guide and tutorial about GPL and other copyleft concepts, we seek help in the following ways: #### Proposing Improvements to the Guide [Merge requests on copyleft.org's gitorious site](https://gitorious.org/copyleft-org/tutorial/merge_requests) to the Guide are most welcome. If you're looking for something to fix, just grep the *.tex files for "FIXME" and you'll find plenty. Many of them are simple and easy to do. Some of them are writing, and some of them are formatting-related. #### Joining Mailing Lists * Subscribe to our low-traffic [announcements-only mailing list](https://lists.copyleft.org/cgi-bin/mailman/listinfo/announce). * Join discussion on our [primary mailing list, called "discuss"](https://lists.copyleft.org/cgi-bin/mailman/listinfo/discuss). #### IRC Discussion The coypleft.org [IRC channel is #copyleft on irc.freenode.net](irc://irc.freenode.net/#copyleft).
