Hi Mark,
Found a little bug in Event app
1. create 2 users which are friends and mutually follow
2. create event (user1)
3. create discussion (user1)
4. answer to the discussion (user2)
5. answer again (user1)
6. Now if user 2 is clicking on his notifications and will reply to the user1's comment, then the comment is not accepted to the answer list in --> Events --> discussions
So ok maybe the response to an answer shouldnt shown in "answer" list, but there should be below the answer comment lines of the answers like in dashboard stream
