I don't want to set up a separate site for each demo, I will have a different subdomain for each demo.
My question is - Can I run a theme on my main site, and different themes on my subdomains?
mydemo.com - runs WP theme 2012
www.mydemosite.com/plumber runs WP theme 2011
www.mydemosite.com/lawyer runs Genesis theme
and so on
I'm too scared to try it in case I stuff things up!
