Override method
public override string GetUserDisplayName(string useruniquename)
  {
   return useruniquename;
  }

I must get Display Name through database connection and query,but
for getting the display name, I am afraid a chat lobby with many users (say 50),
the program will connect 50 times database and issue 50 queries.
When there are many concurrent users, this will surely affect the performance.

Any suggestion?

Thanks,
