- Watched/unwatched a project.
- Tested the watch/subscribe/member relationships:
- Watching implies subscribe.
- Joining implies subscribe.
- Leaving implies unsubscribe + unwatch.
- You can't unsubscribe until you unwatch (slightly better would be unsubscribe implies unwatch, but this is a bit tricky).
- Watched a project, then recevied email about a tagged task without otherwise being involved.
