Remove admin bar

Hi,

Not quite sure where this question fits in, but I'm guessing it's a theme setting.

My question is about the top admin bar. I'm wondering how to turn it on or off
for user sites.

As it is set now, the bar does not appear on sites (which is fine). Rather, all the admin
functions are appearing in the header (not fine). Here's an example:
http://networkingpeople.biz/webventuresites/

What would be ideal, is to enable users to turn the admin bar on or off as they see fit.
Then, Pro Members can have a totally independent Website with their own domain name.

I'm using using the Edu Clean child theme.

Thanks
