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. |

| | 8 | So it might be a question of whether you would want to use the same validations for sites as users? Or should there be a separate sanitize_sitename()? |
