I'm looking for a solution that a chosen blogname is also the main admin name for that blog.
I don't need username registration, so I will rip that part out anyway from the register page.
It's actually quite unlogic that you first have to chose your username, and after it your blogname. It is logical when you need a user usersignup actually.
I was thinking of changing (switching actually) the description from use username and domainname page, so it looks like it's your subdomain page at first and when you submit that that you go to the "domainpage" where I disable the username formfield for editing and $_GET the blogname in that formfield that I have let the user set in my modified "domainpage".
In this way the person thinks he choses his blogname first and his username will be his blogname also, but actually it's the other way around.
Or are there better fixes to do this ?
