I have a User class with two member variables, m_sUsername and m_sPassword. I created this class only a few minutes ago, and before I know it i'm stumped. How do I link a User to the character created by it? Say I just registered and logged in. I've now created a character and want to logout. I logout and log back in again and I want to play as the same character. How would I go about saving the character to that specific User?
