also you can recruit yourself.
Pretty much you pay $35 for a free month and a mount. ($20 for WoW game and first month, $15 for second month)
You can even send the recuit to your current battle.net account and have both accounts under the same email, that way you dont have to remember 2 names and passwords.
I RaFed myself to try out dual boxing
