Hello everyone
I want to rewrite the username profile link and I want the link to look like this username.mydomain.com instead of this member.php?action=profile&uid=1 and when someone access username.mydomain.com I want to show a custom profile template not the default one.
I made the custom profile design and I put it into an external page, now the hard part is to rewrite the url and point it to that page.
my forum is located on a subdomain forum.mydomain.com.

I don't know too much about .htaccess expressions and that's why I am asking here, hope it is the right place.

So you want it like:

username.forum.domain.com ?

or:

forum.domain.com/username ?

Or what?

I want the link to look like username.domain.com
