I need to add custom attributes to the mailing lists: "responsible department": Free text field who is responsible from an organisational pov (not a person but an entity) ... Any hints how to do that best? Is it possible to store custom attributes, or should that be stored elsewhere?
It's possible to do something similar with Mailman 2 - see "Bob's Unofficial Mailman Tricks & Tips" at http://nleaudio.com/bnotes/mailman.htm - I've been using it for years.
In my case it's like the Systers subscription page that Steve mentioned - something to help me decide whether to accept the subscription request, rather than something that I need to store in a database.
When I looked at Mailman 3 last year I made a short custom subscription form which included a custom field, and a script to email it to me then send an email to the listname-subscribe email address.
(I think I must have edited the MM3 confirmation link too because I've found a script that takes URL parameters, and sends a confirmation email to an address created from listname-confirm+ and the relevant token. I can't remember whether that was linked to having the custom field script.)
Best wishes
