I have wanted this extension for so long! Its great! --except that something is wrong. It is not updating Mailman. Everything seemed to load and configure fine. It found my existing mailing lists, members, etc. But when I log in to the frontend as a test user - or real user - and change the email address, it does not update in Mailman or in Mailinglist. I have made sure that all members are in groups and that the assigned Mailing list shows up in their frontend Mailinglist profile... I've changed the email address both in the user account (CB and Joomla user) and I've also tried changing it by clicking the [edit] link in the Mailinglist profile for the user - but nothing makes it pass the info on to Mailman or into the Mailinglist admin pages.
I hope I'm doing something wrong because I love this and, as I said, have been waiting so long for something like this!!
Plz Help!

SOLVED!
It was my fault. I didn't understand it correctly. I just needed to play around with the groups and lists more.

What I found was that each Group is a list of users who can have access to the mailman list or mailman lists assigned to that Group. Its really very obvious, in retrospect. I had populated my Groups but had not assigned any of my mailman lists to the Groups. Hope this helps someone.

I love the component!
