As a PCWorld reader, you should be no stranger to , the free cloud to-do list that works with Android and iOS phones. What you may not know is that RTM also includes a social component for sharing tasks and lists with coworkers, friends, and family members.

To share a list or task with a buddy, add that person to your Remember the Milk contacts list by clicking Contacts, Add Contact, and then entering their e-mail address. They'll get an e-mail inviting them to connect with you on Remember the Milk, and once they confirm the connection you'll be able to assign tasks as shared.

To share a task in RTM, first click the task. In the drop-down menu at the top of the screen, choose Share with... and then click the radio button next to the person's name in the list that appears on the next screen.

To share an entire list, click Settings, Lists. Click the radio button next to the name of the list you want to share, and then click Share with... just as above. Once your list is shared, any items added to it will automatically sync to everyone sharing the list. This feature is especially useful for household lists you share with your family, but it also comes in handy for small workgroups that don't require the bulk of a full project management service.
