I am interested in mainly one topic/categary and wanted to know if there was a way to post via mailing list directly to a categary? (eg AppArmor)
We are using discourse. A popular forum software used by many.
Not a mailing list, but it is possible to subscribe on a per category or per topic case.
In every topic there should be a button o Normal You will be notified if someone mentions your @name or replies to you. that can be switched that lets you subscribe for a topic.
In every category such as AppArmor - Whonix Forum there is on the right side next to New Topic an O drop down button as well that lets you watching a category.
Does that work for you?
That could work, I was hoping for a simple mailing list but this is fine, not complaining! 
Thx for the response/clarification (and a supurb OS!)
