Hi guys, Today i was trying to create blogs on MU WP sites on authority domains (example of signup page: fred.wheatonma.edu/wordpressmu/wp-signup.php) I did 5 attempts with 5 different sites and the result was the same: "sorry, your email is not allowed". I tried 5 different emails, including a corporate one - all clean, not associated with spam or anything... Same result. Ca anybody elaborate on it? How to get through the gate and what is the problem?
