the different IP won't help you. if you registered with a bogus name for whatever reason your only bet is to phase that account out and start over.

there is no sharing, gifting, trading of accounts. personally, i registered one of my accounts under a funny pen name i used. i probably could have went through some insane process to fix it, but i just started over. screw it dude, you want to be 100% legit with this because you're gonna reported and looked into and you can get suspeneded or banned on any or all the accounts. it's up to blizzards discretion.

my advice...TIME TRAVEL RP WORKED FOR ME!
