If you value your character in Bioware’s The Old Republic, in particular the name of your character then you better log in and use it. Especially if you haven’t logged in for a while. Bioware are having a bit of a purge.
Characters below level 10 who haven’t been played in 60 (free) or 90 (preferred) days will need to be renamed, as will characters below level 30 who haven’t been played in 120 (free) or 180 (preferred) days. Characters 30 and above will be exempt across the board, as will all characters of subscribers.
