The #Help channel on that network is a more appropriate place to ask, however:
Use
/nickserv register password-HERE [email]email@address[/email]
So *IF* you wanted your password to be "cookie" and your email address was
something@someisp.com then you would put:
/nickserv register cookie [email]something@someisp.com[/email]
This will register the nickname that you're using, you do NOT have to specify the nickname in the command. It's likely that an email will then be sent to the email you provided for confirmation of the registration.
REMEMBER: do
not use the exact example above - 'elephant' is one of the most common passwords in the world. Do NOT have your password set as 'elephant' or the word 'password' or have it as your nickname. Also, do not use that example email address use your real, working valid email address
DALnet has a good guide to
choosing a safe password.
Further help on this issue should be asked in the #Help channel of the network you use!
G'luck!
