T299657 introduced a generic notification to make people aware when one of the following things happens to a discussion they are subscribed to:
1) The discussion is **moved** to another page
2) The discussion is **merged** into another discussion
3) The discussion is **deleted**
This task involves the work of enhancing the notification T299657 introduced by offering people the ability to:
- See the name of the page the discussion they were subscribed to was moved //to//
- Visit the discussion they were subscribed to on the page it was moved //to//
- See the diff that added the discussion they were subscribed to to a new page/different discussion
=== Story
**When** a discussion I am subscribed to, and expecting to receive notifications about, is moved to another page or merged into another discussion, I want to be made aware A) what page said discussion was been moved //or// B) what new discussion the original discussion I was subscribed to has been merged into, **so that** that I can recognize future notifications about said discussion as being from the discussion I'd originally subscribed to.
