I need to be able to add client users as responsible for completing tasks. It is not allowing me assign client users to a task because the task is flagged as internal. Even when I flag the tasks as external, it will still not allow be to assign.
All this said, when you flag a task list as external it does not allow you to associate the task list with a Milestone, which is absolutely ridiculous. If the completion of a milestone is predicated on an upstream task that needs to be performed by my client, why can it not be associated with a milestone. Who's crazy idea was this zoho?
