Below is a list of variables compiled by Mark Niemann-Ross and posted on his blog.
<MM-archive>Archive> This is an Open tag used to create a link to the mailing list archives.
Proper use would be...<pre php><MM:
<MM-archive>here's a link to the mailing list archives</mm=archive>
Typically this brackets the MM-List-Name tag
<MM-Case-Preserved-User> A mystery tag. Appears on the subscriber information page, but is blank in my installation. Appears to be used with <MM-Disabled-Notice> and <MM-results>
<MM-globalGlobal-changeChange-of-address>Address> Checkbox used on the subscriber information page. Use this inside of the subscription change form. When enabled, will change the email address for all lists subscribed to on this list server.
