YICS Isn't a Chess Server

Yahoo! has introduced a CAPTCHA test for access to their Games services. As YICS is a text-mode program, there is no way to reliably present the challenge to the user.

This project is therefore temporarily defunct. If a workable solution emerges it will be applied, but I haven't the time to solve this issue right now.

Thanks to all of my loyal users and contributors. We'll be back someday.

It has come to my attention that several people are violating the GNU General Public License with respect to the YICS and Y to ICS codebases. These people are usually not United States citizens and have little available contact information, making it difficult to inform them of the violation.

When I find such sites I will list them here along with a detailed explanation of the offenses against the GPL and my copyright.

It should be noted that according to section 4 of the GPL: "You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance." These parties are not in full compliance and their rights under the GPL are therefore automatically revoked, and they may not distribute YICS or Y to ICS in any form. If these parties come to me and demonstrate that they wish to become compliant again I will reconsider licensing the software to them again.

If you have any information on how to contact these parties please drop me a line at <cdhowie at nerdshack dot com> and mention "YICS" in the subject.
