Yep WinRar is completely free to use. It will ask you to pay for it but you don't need to, just ignore it and keep using it. If you decide to pay for it that is up to the user, but I have been using it for around 5 years for free.
How do you change the name of your character, it doesnt allow me to back up and delete the genaric Dreamer Name. I might be missing something on the generated keyboard.
