In there you will find... 1. Multiple accounts per person are not allowed. 2. Family members can play simultaneously given they play on the same realm and are actively playing. If you need an afk for over 10 minutes then log out. You will be tested and banned if not. 3. You cannot use the other accounts to log in another realm to bypass the switching timer.
Hope this helps, although step 4 of setup is READ THE RULES.
"There may only be one account per person. Measures are incorporated to detect multiple user accounts. This includes creating an additional Phoenix account when banned or suspended."
