Syntax: /nickserv LOGOUT (nickname (REVALIDATE))

Without a parameter, reverses the effect of the IDENTIFY command, i.e. make you not recognized as the real owner of the nick anymore. Note, however, that you won’t be asked to reidentify yourself.

With a parameter, does the same for the given nick. If you

specify REVALIDATE as well, Services will ask the given nick to re-identify. This use limited to Services admins.
