Hello, and sorry for replying on such an old topic. I couldn't find a FAQ about the forums rules if posting on such old topics is forbidden.
I understand that an addon with All rights reserved should not be copied, but would the moderators allow a copy of an abandon project with small changes to make it functional with the latest patch? I did try to contact the Author about one year ago, and I just send him another message with my new account, but I don't think he cares about the project any more.
I'm also making a similar addon with a more permissive license, but until i'm done with it, since it's also my first time working on a WoW addon, I wouldn't mind giving something functional to other people.
