[Mailman-Users] How To Change Header and Footer

[Staven Bruce]

Newbie Question:

We are using the latest version of Mailman on a RedHat Linux 8.0 box,
running the latest version of Sendmail as the MTA. I need to add a custom
header, which includes our "logo" and "branding", to the HTML pages for
every list. I have also been asked to remove the GNU and Mailman logos from
the footer of all the HTML pages. I have tried the admin pages for editing
the HTML and I've gone through the HTML pages in /var/mailman/data. However,
I still haven't identified where to make these changes. Does anyone know?
Has anyone done this before? Any info would help!
