I am a PHP programmer, so what I'm asking should be done with PHP.
I've got a web based subscription service. What I want to do, though, is create subdomains and email addresses for somebody when they sign up for my service.
If a user comes to my site and signs up with the username mike123, I want to automatically create a email@example.com and the subdomain mike123.mysite.com. Is there an easy way to make this possible?
