If you wanna register your nick type in message board:
/ns register your_pass your_mail
Example:
/ns register kuki22 kuki@zwd.com
When you type this, you should get e-mail from axenet services with code to confirm your registration. Copy code, paste it to your message board and send. That's All. Now always when you connect to the Axenet you must type this command:
/ns identify your_pas
Example:
/ns identify kuki22
