First of all, I'm not looking for some piece of code (that will help, but I want to learn).
I'm trying to make an email program. Not for distribution, just for learning. I've already got the encryption ready. What I want to be able to do now is add users and store their settings somewhere. That will include the username, email, and password (and some other small stuff, but this is the main stuff).
What do you guys think that is the best way to store these settings so I can call them in the program?
