@Isaac In general to contact list owners you can mail the special address like research-internal-owner@lists.wikimedia.org

But I can tell you that resolves to:

ahalfaker@wikimedia.org
jmorgan@wikimedia.org

and both of these addresses do not exist anymore.

So yes, you need new admin addresses. It should have been part of offboarding users to hand over their admin rights to a new admin.

Once you have new admin email addresses for us let us know and we can add them and then reset the password so new admins will get access.

Thanks for the quick response @Dzahn ! I emailed the list to ask for nominations and @Ladsgroup graciously volunteered so we will be the two new admins. If you could add the following as admins, that'd be much appreciated:

ijohnson@wikimedia.org
ladsgroup@gmail.com

Let us know if there's any additional info needed etc.

@Isaac @Ladsgroup I replaced the admin addresses and then ran a shell command to reset the password to something random and mail it to the admin addresses. So you should have both received an email from mailman now that let's you login at the admin UI. Keep in mind there is only one shared admin password and they are not individual for each admin. Optionally you can change it to something else but need to tell each other about it. Cheers, Daniel
