I try to register my nickname on freenode with this command:
/msg Nickserv REGISTER secretpassword nickname@gmail.com
I do get a confirmation that a email was sent to nickname@gmail.com but there isn't an email in my inbox also not in SPAM folder.
The output of /msg Nickserv Info told me that my nickname registration is not completed. Is there any limitation on freenode IRC while using gmail or can I change the email address for the registration process?
