I hope you don't mind me asking another question. What variable would I use to delete subscriptions for all members of a usergroup?
The reason I'm asking these questions, is that I have many old inactive members, and the forum keeps sending them birthday greetings and emails with updates of threads they have subscribed to, but many of these emails bounce back (and I fear they are flagged as spam). So, I have installed
This mod, which enables me to put them all in one group, so I can delete all their subscriptions and turn off admin emails (if people hasn't visited for more than 2 years, I see no reason to keep sending them updates and birthday greetings).
