I want to make my site have wild card domain names. Does anybody know how to do this with .htaccess? thanks in advance.
You can't do it with .htaccess, it's done with DNS and Apache, in cPanel you use * as the wildcard part of the domain. Just pop a ticket in to your host and they should be able to sort it out for you. .htaccess only allows you to apply rules to handle the request in different ways e.g. route to a PHP script.
