Various questions...

1. Is technically possible to improve the phrase?
   Two thread merged: Merged the threads “Title 1” AND “Title 2” into the thread.
   Three or more threads merged: Merged the threads “Title 1”, (comma) “Title 2” AND “Title 3” into the thread.
   
2. Merging a thread does not display a log entry in the thread (visible to all users as when a thread is moved to another forum).
   Is this the expected behaviour?
   
3. Merging a thread deletes the previous log entries. The entire moderation log of posts previous to the merge is lost.
   Is this the expected behaviour?
