Request Crimson Warden
Bring Crimson Warden to your group
Send the three links below and the owner will review your group and get back to you. Ask about pricing or anything else in the notes.
What happens next. Your request goes to a private owner inbox. Nobody joins your server or group automatically, and sending a link doesn't prove you manage it: the owner checks that by hand, and setup later asks Discord and VRChat to confirm it.
