My friend has an account which does not play more, he stopped playing maple. I know it's against the rules Sharear accounts, however, I think sharear would split the bill for XP and items at different times faster. If my friend does not play more, I may or may not use the account he had ?! I hope answers. =]
Only your friend is allowed to play on his account, even if he quits playing nobody else is allowed to log in and play on that account. This means that you are not allowed to use your friend's old account.
