Quote from Bob Smith :

Faib227 - to clear things up, if you now have access to your brother's account, and he is no longer using it (at all), then it is his choice to give you to his account. Of course, he can't have given you the account with also giving you the password. If you are to become the new owner of the account, then you must obtain the password for the account, then you can log into the forums with that account, and post licenced content without issue.

Yeah that is what I figured.

I've been trying to get his password since I created this account. but he doesn't remember it.
