If you want to assign a task to a user, download and install the Joomill Admin Checklist Assign To plugin like any other plugin. The plugin is activated automatically upon installation.

How does it work:

After installation, you'll find an "Assigned To User" field on the right-hand side of the task edit screen. Select the user who needs to perform the task.

In Task Management and the Checklist view you'll see an "Assigned To" column, which you can also use to filter tasks per user.

In the Joomill Admin Checklist Module you can enable the "Assigned to me only" option. The module then only shows tasks assigned to the logged in user, and hides categories you're not assigned to.

My Tasks

Available since version 1.6.0. Next to the per-user filter there is a My Tasks filter in both the Checklist and Task Management, which shows only the tasks assigned to you. It saves picking your own name from the user filter every time, and it keeps working for every colleague on the same site without them changing anything.

The filter appears as soon as this Assigned To plugin is enabled; without the plugin there is nothing to filter on and it stays hidden.
