Create a group for Tasks

Create a group for Tasks

Hello,
I am trying to create a group for tasks.  The goal is to create a "manager" group, then I could assign tasks that would be visible to all the managers.

When I log into webmail, and select Tasks on the left, I see groups.  Unfortunately, there is no PLUS sign for me to add or create a group.

I then logged into the Control Panel, and created a group there, but I still dont see the group under tasks.

Thoughts?
