In the near future, we will be doing another full reset of the beta database in order to test new changes. This reset will wipe the following information for all players:

• Character and identifier
  
• Friends list
  
• Profile
  
• League placement
  
• Ladder rank

Due to the amount of people currently participating in the beta, this database reset will allow us to monitor and test conditions similar to a game release (albeit smaller). We want to thank everyone for their patience and continued help and support in testing StarCraft II.
