Maybe instead of titles there will be a badge sytem, kind of like nameplates on Reach. There could be badges that are unlocked by achieving different milestones based on how long you've been a member, post count, Destiny achievements, etc. These badges could be displayed on forum posts and in-game on Destiny somehow. Maybe the above pictures is a picture of one of those badges. I'm almost definitely wrong, but I've been thinking about this for a while now.
