There are two ways to confirm your subscription: by email reply, or by web hyperlink.
To confirm by email reply: Press the reply button in your email and type the word OK in the body of the reply. Leave the subject intact. Send the message.
To reply by web hyperlink: Find the text near the top of the request for confirmation that reads, "To confirm the execution of your command, simply point your browser to the following URL:", followed by a web link. Click on the link to confirm the command. This should bring up your browser window, and you should see an acknowledgement that your new password has been accepted.
After confirming your password, press the BACK button in your browser to return to the LISTSERV Login Screen. You should now be able to log in using your new password. At this point, you should see the main archive page for the list you have selected.
