Add site menu on Global Dashboard

Hi everyone!

I want to talk about dashboard signup option.When user register to site and if they choose “only username,please” then they logged in (sitename.com/wp-admin/user) there is no add site option.

Sure,they can go sitename.com/wp-signup and then set blog info but I guess dashboard menu item need for this?

What are you think about this?

And how can add menu item if user haven’t any blog.

Thanks.
