Unfortunately no… It's UNLIKELY that any of you guys can "sign up" (If you're an Outlook.jp, Hotmail, Zoho Mail, your own Domains as your Email, etc. if you DON'T have Emails that Yooco.org allowed) + Along with ANY other sites made with Yooco.org｜However, you can change your Email into any of these (If you have Gmail, Yahoo/MyYahoo, Outlook.com, Yandex.ru, Mail.com, Inbox, Fastmail, Airmail.cc, etc.)

It's for someone who have "Multiple Emails" (If the Email of yours that has something that you're UNCOMFORTABLE with, then "keep it to yourself")

Don't worry about it, we will give you "Admins Rights shortly", but then take it away whenever you're finished changing your Email Address
