The basics of the Protected Node installation are easy:
Once you have installed the module, you probably want to change the permissions. Permissions allow your users to access the Protected Node functionality based on their roles. Please, see the point about Permissions for more information about those.
Now, you're ready ...
The
Snap! system gives different people different privileges on your website. As the administrator, you can offer other users to become authors and editors.
The privileges are defined in each user account.
IMPORTANT
When you first install the module, I wouldn't be surprised if you'd want to create a To Do List item right away and then assign the task to one or more users.
It won't work.
This page documents the usage of the To Do List module to end users (i.e. not how to install and setup the module, but how to create To Do List items, share them, mark them started/finished, etc.)
For administrative information check out the To Do List module help.
Once installed the module offers several permissions under Administer » User management » Permissions (admin/user/permissions). These are include permissions similar to the Node permissions and some others. All the permissions are explained below.
Additional permission granularity can be obtained with the use of other modules as defined in the Extend To Do List.
The permission functions properly, no issue in that regard. However, the name of the permissions should be using "to_do" with an underscore to be 100% compatible
The To Do List module can be extend with the use of other modules. This page describes such extensions and what you can do with them.
You may want to allow more people to work on your To Do List with better granularity in regard to who can edit which issue (instead of all of them) and who can view issues.
There are two modules you can use for this pupose. One lets you choose based on a set of taxonomy terms and the other lets you choose based on available roles.

This is a quite interesting article which I thought I should share and keep a copy of!
Most of us, even if we can determine whether a piece of software (or hardware!) can be hacked, we just do not have the time to spend on testing each device we use to ensure that no hackers will be able to get it. We rely on the manufacturer to do that work for us.
This article shows that even though all manufacturers have protections, all are vulnerable! And that means your data is vulnerable on your cell phones... Hope this does not scare you too much!
