BK: As long as they update a notice on a MUGEN site every 3 years (that's a lot of time!), he can protect his work. If he doesn't care enough to do that, then he doesn't care about his work either. Syn: The site is still up with the restrictions in place. That is still valid to me. When the site eventually goes under, then the restriction goes as well. Also if someone has copyrighted something with the relevant copyright office, and covering all nations, then obviously the law would cover what happens as well.
