The To-Do Lists tool allows you to create an unlimited number of to-do lists in order to track action items from meetings, plan upcoming events, and more. This tool can be by organizations in their portals but you can also setup personal to-do lists. To access your personal to-dos, click on your name in the top right of the screen and select To-Do Lists.
The resulting page serves two purposes. First, it houses the option the create personal to-do lists. These lists are only available for your eyes and do not have any connection to the organizations you're a part of. Click here for any questions about managing to-do lists.
Second, it congregates all of the tasks assigned to you across your memberships. These will appear on the bottom half of this page. Click the arrows to view more information about each task.
