ha, right, its subdomains that i want.
after googleing this i realise i'm stepping into another minefield here.

all i'm after doing is to create a subdomain of 'username' instead of '/username' for a members area.

i would normally simply use mkdir("username", 0700) etc to make
a unique folder for each member (mainly for their images)but this fills the root directory full of folders so instead i'm looking at maybe using these subdomains?

is there a quick & simple way of using php to create a subdomian
and if so, what would the path to the image be?
