How do you Get Free IMVU Avatar Name

I am a member of imvu and i think their is no way you can get a free avatar name. The only way to get a free one with guest off your name is if you buy a Prepaid Card from local stores Like Best Buy and Target. I buy prepaid cards and my guest on my avatar name is gone. So your best way to get it free is to buy a 10, or 25 dollar imvu card and Hey why not you get to go shopping too.
