My goddaughter used my new WiiFit before I had a change to. I can't figure out how set myself up and now I can only use her profile. I do erase and start fresh?

Whoo woo, just got o the mii channel and set up yourself. Then you will also see your niece on various games as a friend as well as anyone else you set up. We have only had the Wii a few weeeks and we had a party one night where we set up about a dozen friends...now they show up as audience and other players in Wii games...don't erase her.

Yes, just create your own Mii on the Mii channel. It's fun to make a Mii and you can always change it later. We had a blast setting ours up. My hubby is Fat Elvis and my son is the only bald guy with blue eye shadow I've seen lately. I even set up the cat so she can run with me. It's fun when you're doing your games to have Mii's you recognize along the way. In cycling you can try to run over family members!

Once you create your Mii's on the console they can be used in other Wii games.
