Processes new site registrations.Checks the data provided by the user during blog signup. Verifies the validity and uniqueness of blog paths and domains. This function prevents the current user from registering a new site with a blogname equivalent to another user's login name. Passing the $user parameter to the function, where $user is the other user, is effectively an override of this limitation. Filter {@see 'wpmu_validate_blog_signup'} if you want to modify the way that WordPress validates new site signups.
