I think he's referring to the lack of a registration button altogether now.I think the logic behind the email blocking system is to block out trolls and deture multiple accounts. Do you have a pay email adress like roadrunner etc.?
Refer to the above posts; that wasn't the issue.You have to have a paid E-Mail address- free ones such as hotmail.com, rocketmail.com, gmail.com, etc., will not work anymore for the Magic Cafe.
That sounds like a likely cause; if their email requirements weren't effective, then it's possible they just disabled all registrations until they can figure out what to do about the issue.They were having some problems with heavy spammers, bots, and trollers, if I remember correctly.
