I'm wondering if someone would be able to please tell me where I go to find out what CWs are classified as public or private please?
Thank you!

Since it is a user coined term (there is no official acknowledgement) you would need to either try Googling it to find the release post, or just ask the person who released it.
[edit] You got a forum point while making a post! Check out the shop here!
so there's no other way, hunh? Okay, at least I can try asking on the "who made this thread" then, in regards to trying to track the releaser down. Thanks

None that I can think of! Usually the people who are on that thread are particularly skilled at knowing if something is private :) good luck!
