Currently, you only get alerts in your inbox if someone replies to your question, leaves a comment, or you get a chat message (and probably a couple more that I'm missing).
It would be nice if you got alerted in the inbox for the following events:
- question/answer gets edited
- question/answer gets deleted
- question gets closed
- question gets migrated
This way we can get more transparency on what happens to our stuff without having to go to each site/question individually.
