* The Contacts- mod does not actually support displaying the Hidden, Contacts- Worlds.
This is a mod that adds the option for you to be in Contacts- Sessions in Neos!
That's right! Only people who aren't friends of someone in the session can join! - Isn't that fancy?
But keep in mind that you'll need to inform others of the contacts-minusness of your world manually since the mod can't make other people's clients display it in the contacts menu.
To use this mod, you will need the NeosModLoader and a settings mod of your choice, such as NeosModSettings.
The modloader is needed to run the mod, while the settings mod is necessary to toggle the contacts-minusness of your sessions on and off.
