plugins – In a WPMU that uses several different domains, how to enable users to register subdomains of any domain from the main site?
For example, MainSite.com is the main site for the WPMU installation. Site1.com and Site2.com are added as blog sites with the MainSite.com WP network admin tool. Is it possible to enable a user who registers on MainSite.com to pick their own subdomain for whichever site they choose (User.Site1.com, User.Site2.com, etc.)?
