Disclaimer

World of Warcraft is a trademark of its owner. Private-server notes are about addon folders, not an invitation to download a client from us.

Scope

Blizzard Entertainment publishes the official client. Forever, Midnight and Classic pages describe that client. Private-server pages describe other people's 3.3.5a and 1.12 clients. They are not Blizzard realms. This site hosts neither client.

Nothing here is legal advice about Blizzard's terms. Read those terms on Blizzard's site before you decide what to install.

Questions

Are private servers endorsed?

No. The pages exist because people search the addon question. They do not endorse a realm.
