Hi,
In Warsaw there is question about e-mail notifications, we recieve notifications of new activity on wall or in points but there is no notification when someone will coment it, even if we come t it already.
I could not find answer anywhere, is it bug or a feature? 
You won’t get notifications about replies in a conversation unless you’re the one who started it or replied to it. There is a bell/e-mail icon on the top of each conversation to show which kind of notification you get, similar to the one on place walls like this: Introducing store wall and store subscriptions - #32 by bruno. But I think it’s a bit misleading because, as I wrote above, you won’t get any kind of notification for conversations in which you don’t participate.
Does that make sense to how your group is using Karrot?
