While I am disappointed that Bungie left in-game group and clan making out there is a solution. 1st things 1st, stop with the random invite's! IT's annoying when you don't put anything in the invite. Utilize the tools the game has. send Invites with a message like vault of glass or nightfall help. This really helps people decide if they want to join you and stop what they may be doing already. In the Rosters screen, choose the option view profile and send the person a message for help or to join up. I've helped people in the past through this method and made many friends. Or .. you could go through Bungie.net. So share with others in the community how to get around these social streets of Destiny so that we can all help each other and stop the normal MMO random propositioning. See ya all in the game realm. Peace.
