Why not? If you make them all the same, it should be easy. My passwords are the same. The only ones that aren't are the one for my email, which my dad chose, and the one for my computor, which I don't want my brother to guess.
But if you're serious about not wanting to join, that's fine with me. Would like to join me and Zelda64 on the chatbox? You don't have to be a member and we're bored.
