Here are the changes to nickserv:
Go to line 755 and the line there should look like this:
/nickserv set email Password [email address]
The added part is the Password
Then go to line 771 and add there to the command:
"ILovePeanutButter"
to represent the PASSWORD.
Thats all.
For information about it msg me online to clarify it if you have questions.
