As for now (0.08) a task can be assigned to one or more persons.
The problem ist: i cannot state who is responsible and who only participates. THis leads to tasks not getting done.
I think it should be something like:
- a task has at most one(!) responsible person
- it may have other participants
- (optionally) it may have a "nosy" list
taking this as a structure element of the notification emails would be a great implrovement, eg something like:
- "Changes in my tasks"
- "Changes in tasks i participate"
- "Changes in tasks i am interested in"
- "Other changes"
