The "owner-supplied" welcome message can easily be removed.

- Select the Mail Templates tab.

- Click Revert to set it back to the default of no text.
The LISTSERV administrative welcome message is more difficult to clear. See Section 9. Creating and Editing LISTSERV's Mail and Web Templates of the List Owner's Manual for detailed information about LISTSERV templates. You will need to add the ".QQ" command to cancel the message(s) by adding it on a line by itself to the Signup1 and Add1 templates. Note: Signup1 is the note sent to self subscribers and Add1 is the note sent when the listowner subscribes a person.
