Can anyone tell me whether it is possible to automatically Assign a user to a "Joomla Group" when they subscribe to a specific list?
I'm not sure if it meets your needs, but you could try this plugin: https://www.acyba.com/acymailing/399-acymailing-plugin-usergroup.html
Spot on thank you!
You're welcome, enjoy your Acymailing!
That link isn't working. Is the usergroup plugin available anywhere?
Just tested the link and it's functioning normally. Can you try again?
