landing site for each domain ?


First, it's a great plugin !

I'me using 2 domains on my WP 3.0.1 multisite

Is it possible to create a défault landing site for each domain ?
http://www.domain1.tld and http://www.domain2.tld or better domain1.tld and domain2.tld for example ?

i see that www was prohibited for blog creation and i can't change it.
I try to create domain2.tld but i have to give a name to create a new blog.

Any idea ?

Best regards
