DCUO reclaiming inactive names this month
SOE will be releasing inactive character names for current DC Universe Online players to claim "shortly after January 20, 2015." If you haven't logged since July 20, 2013 -- that's 18 months ago, for what it's worth -- your character names will be appended with an underscore and a roman numeral. SOE says that accounts and characters "will remain otherwise intact" and that no deletions will occur.
If you want to be that guy who saves names in games he doesn't play, you can simply log in once prior to January 20th. But you're not that guy, right?
