...the best bet is to post ZooSchool stuff and if they don't like it they will complain to midnitecrow and he can then update us on the situation.
I believe ZS closed down because they were a commercial site and needed to make a profit to survive. With the ban on beasty sites by all the major credit card companies the flow of cash ceased and with it apparently went the whole ZS operation.
When Ark after Dark went the same way their movies became common property and are now posted freely. Unless ZS decides to tell us otherwise my guess is that their movies are also fair game now.
Time will tell.....watch this space
