If you change your nick, then change it back, unless it's grouped you have to change it back, release it (sometimes), then verify.
I decided to use aliases to make it easier.
/id msg nickserv identify PW
/die ns Release Name PW
/kill ns Ghost Name PW
/change Nick Name
You can probably get what each does...
I am wondering if there is a way to combine /die, /change, /id into one aliases?
