As a new user you are not given a star wall which means that anyone who wants to send you a private message is able to do so. If you would prefer to have a wall please go to Settings – Security and Privacy – Setting the Amount under "Who Can Message Me". Set the amount you would like people to pay you in stars (Eclipse Currency) to gain access to a dm with you. This will add you to their friends list. Please note that no user will be added to your friends list automatically it is not synced so if you would like to keep chatting feel free to add them right back. Eclipse gives you the right to either accept messages from other users on the app by lowering, removing or increasing your wall at any time and you do not need to have any stars to set this up. Should you wish to receive private messages from any user on the app at any stage you can set this back to zero.
