'Post announcement' allows you to post messages and email your class, and is visible on your main course screen. Any announcements you post will be displayed to the student when they first log in to Quest on their courses list. You can also choose to email students with this function.
If your students have provided current emails to the UT EID system, you can push the posted announcement out in an email to the whole class. Students can update their contact information by updating their EID profile through the UT EID Self-Service page: https://idmanager.its.utexas.edu/eid_self_help/ and clicking "Manage My UT EID Profile"
