I was wondering if there are any ways to make sub-sites have the ability to register its own users. Consider example.com as the super admin site, and example.com/123 as the sub-site. If I go to example.com/123/wp-signup.php I will be redirected to example.com/wp-signup.php.
I haven't been able to find a plugin to stop this. I'm also doing domain mapping which is why I want to hide the super admin domain. The domain mapping also does not help the redirecting. It seems to be a core thing.
Any help is appreciated!
I have WordPress version 3.0.3.
