As far as I know, this list doesn't have a message command interface. As a result,
you'll have to subscribe to the new address and then unsubscribe the other address.
To shorten your hunting, subscibing is done thus:
"You can sign up for the AbiWord development mailing list by sending a message to
[EMAIL PROTECTED] with "subscribe" in the message body." After the
joy of a three part subscription, you can unsubscribe the other address as according
to the first "Welcome" message:
If you ever want to remove yourself from this mailing list,
you can send mail to <[EMAIL PROTECTED]> with the following
command in the body of your email message:
unsubscribe abiword-dev
or from another account, besides <[EMAIL PROTECTED]>:
unsubscribe abiword-dev <[EMAIL PROTECTED]>
