Can someone help me with an .htaccess question?

I have an old expired domain that use to have subdomains. I want to setup something where if someone tries to go to an old subdomain it redirects to my index.

Site is http://nowgo.net/index.php
I would like to wildcard it if possible, something like *.nowgo.net redirect to the index page.

Can someone post the code that would be needed?

 

Here you can find the redirect method you are looking for: how-to-redirect-a-webpage

 

Gracias mi amigo.
