If you played the original Guild Wars and would like to reserve your character names from there for Guild Wars 2, you have until July 31st to do this. Make sure you have logged into your Guild Wars account at least once in 2012, and you can reserve your names there, they will only
be reserved for the headstart 3 day period.
Once the early access timeframe is gone, Arenanet plans to release the reserved names for new Guild Wars 2 players to use. So don’t delay too long if you want your names carried over!
