Please, can you add a notification when friends and tribe members log in? It would enhance gameplay a lot to know who is on and when. Sometimes a tribe member will be in game and I don't know for 30-60 minutes because they are out of visual range and happened to be afk when I said Hi after logging in.
The social aspect of this game is SO important. If you don't have the tools to bring people together and interact more, it will be difficult for a social network to form in the game. No social network = dying game.
