The devs should open the door across from the Speaker and in that is like an in-game LFG. From there you could go up with your character and put what you are looking for. From there you would get notifications from your ghost with responses. For example if you needed a group for a nightfall , go to the room and put yourself on the list and bam when other people are looking for the same thing you would have the option to "ping that player. Ther should also be some type of filter as well for ex: light level and character type (Titan , Hunter, Warlock) this is just a small sample of what I would like to see.
