Hello,

Let us say when a user signs up, I dedicate a sub domain to it. So to  
do this do I need to use routing or something else? Will I be able to  
test it on ‘localhost’? Will their be server settings that I’ll need  
to change?

Any help or link to tutorial or documentation would be appreciated.

With Warm Regards,  
Thanking You,
