What happens to members accounts

Apologies for the confusion. Our internal name for the categories is communities, so we will have various community categories. So for example we have a Education and Training Committee, who have an Education and Training Community, but the community networks and asks questions via their Discourse category.

So it sounds like if a member leaves our organisation, they will still have a Discourse account, but we can restrict them from viewing all our discussions in all of our categories?

Many thanks
Marie
