 the username is used for the default sitename slug. So to prevent bad
 URLS, we sanitized everything to match.

 The create_new_blog() function uses sanitize_user() to sanitize the
 sitename, so the same filters used for users would be used for sites. But
 I am not seeing anywhere that there is a fallback to the actual username.
 During wpmu_validate_blog_signup() it checks new site names and does its
 own separate lower string check.

 It seems that removing the strtolower from sanitize user does the trick as
 long as that is the desired effect?
