Im sure you guys are already working on the (Help new users videos) But why not let the community help the community? Make a public Menu. It’s basically a fake working menu that can be navigated but douse nothing. This way Users can show other users how to use the Menu. The Menu will have a little dot that can be used to point at things for the other user to see.
This Menu would not show the users worlds or avatars or any personal info.
