Slowly untangling us from various split / merge bugs has been on our list for a while. @Osama can you take this?
When you post a new topic it is always considered “watched” by you. So we should also force you to watch it if your new topic is a result of a split.
Eg:
Topic 1 (sam is watching):
- Sam
- Bob (split here)
- Jane
New Topic 2 (bob is watching)
- Bob
- Jane
