One of the main conecpts of ZeyOS is to share information. Instead of forwarding messages and documents, ZeyOS provides objects to every user. If you want to change the visibility of an object, you can change the ownership. This works for any object throughout ZeyOS.
Let's look at a message: If you want to change the owner of the message, go to the field and delete the current entry.
When choosing your username, this object will be private, if you want it to be accessible for everyone simply choose public.
