I just had a great discussion with wiziwig over at
www.supermod.org and he has agreed to make an adjustment to his license to ensure that mod writers retain their intellectual property rights.
I think this is really a win/win for everyone. If you are approached by supermod to include one of your mods in their release, I would encourage you to do so. Supermod provides a great service to those forum admins out there that wish to have their boards modded but do not have the technical skill set to do so. Just make sure that you explicitely state to wiziwig that you wish to retain your IP rights, and he will make sure to accomodate you.
