We recently had a request about the “Create a New Task” and “Add Yourself to a Task” functionality and wanted to share our response.   Thanks to Rich for putting this together.
Enjoy.

Both of these are controlled by the permission to “Create New Task or Assignment”.

I’ve included a series of illustrations that highlight this point followed by the procedure for a PWA Administrator to change this setting.

PROCEDURE

If you want to enable the “Create new task” functionality for members of the Team Members group your Project Server administrator would need to do the following:

1. Log into PWA with Administrator permissions.
2. Click the Server Settings link in the Quick Launch menu.
3. Click the Manage Groups link in the Security section of the Server Settings page.
4. Click the Team Members group to open it for editing.
5. In the Categories section of the page, click the My Tasks category.
6. In the Permissions for My Tasks data grid, select the Allow setting for the Create New Task or Assignment permission.
7. Click the Save button.

This procedure can be used to control the permissions for the Create New Task functionality in any security Group.
