The e-mailing of outstanding tasks is not present, but I agree, it
could be useful. Maybe every time a task goes Overdue, an e-mail
alert?
As for assigning tasks to people, you do so under Collaboration tab.
You can set public TODOs, or add named of Collaborators much like you
would add projects, and set tasks under them. So far, there is no way
to flat add a Collaborator to an existing task, but I found a not-so-
annoying work around. Simply add a collaborator, make a dummy task,
and f you go to the Tasks tab, a new "person" column will appear. Feel
free to type in the names of the Collaborators, and when your done,
kill the dummy task.
Sadly, the "person" column does not appear on the Projects, Deadlines
or History page, which I would like to address. I've forgotten who I
assigned to what, and clicking around to find out who is less than
productive.
