How do I post a sub-account announcement?
Department Administrators that have delegated access to their sub-account can post an announcement to any (or all) users having an account on any site within the sub-account.
The sub-account announcement is posted on each individual user's Dashboard and can be dismissed by the user once read. You can also choose to have the announcement sent to users as an email notification.

Note: The example here is for a sub-account named "Canvas Demo Courses". Your sub-account will reflect your delegated access (Example: Biology, Chemistry, Economics, French, Education...)
This displays your sub-account administration page
 In the Title field, type the title of the announcement.
 In the Announcement type field, set the Announcement type (warning, error, information, question, or calendar). Refer to the Canvas Global Announcements Document to see examples of the icons.
 In the Message field, create the announcement using the Rich Content Editor. The Rich Content Editor includes a word count display below the bottom right corner of the text box.
 In the Send to section, select the roles of users who should see the announcement. You can select both course and account roles. If no roles are selected, the announcement will display for everyone with a course in the sub-account.
Choose the start and end dates for the announcement by typing in the fields or selecting the Calendar icons (required). The announcement will appear on user dashboards on the Start date and time you select. At the End date and time, it will no longer appear on user Dashboards but can still be referenced on the "Recent Announcements" page.
If you would like to send a notification to users at the announcement start time, check the box for "Send notification directly to users when announcement starts." Unless a user has changed their default notification preferences, they will receive the text of the announcement in an email to their Tufts email address.
